BFCM 2026 Seller Fees: Shopify vs Amazon vs Walmart

Black Friday is November 27, 2026, and Cyber Monday is November 30 — two weeks away. If you sell on Shopify, Amazon, or Walmart, the biggest threat to your Black Friday weekend is not a slow website or a sold-out bestseller. It is the fee stack you agreed to months ago and never re-priced for.

Here is the short version: Shopify charges no commission and no holiday surcharge — you pay your normal payment-processing rate. Amazon charges a referral fee of 8–15%, plus a holiday peak fulfillment fee averaging $0.32 per unit from October 15, 2026 through January 14, 2027, plus a 3.5% fuel and logistics surcharge, plus storage that triples in Q4. Walmart sits in the middle: 6–15% referral fees and Q4 storage that triples for inventory held over 30 days.

On $4,000 of Black Friday revenue — one hundred orders of a $40 product — the fee difference between the cheapest and most expensive channel is nearly $900. That is the difference between a profitable weekend and a weekend that only looks profitable until the payouts land. This guide works out the real numbers, channel by channel, so you can set your discounts with the fees already subtracted.

The fee calendar: what changes, and when

Most sellers get tripped up because the fees do not all change on the same date. There are two overlapping peak windows, not one:

The storage peak and the fulfillment peak are different windows. Amazon’s standard-size storage jumps from $0.78 to $2.40 per cubic foot for October through December — roughly triple — and reverts on January 1. The fulfillment peak, the extra charge on every unit Amazon ships, runs October 15 through January 14. An order placed on January 10 but shipped on January 15 pays the lower rate, because the fee is charged when the unit leaves the fulfillment center, not when the customer orders.

One more date for your calendar: Amazon announced its 2027 fees on November 5, 2026. Fulfillment fees rise by an average of $0.19 per unit from January 15, 2027, and storage becomes a single age-based rate on February 1, 2027. If you are planning January restocks, the 2026 peak rates are not the rates you will pay next year. We break down the full 2027 schedule in Amazon FBA fee changes January 2027.

Shopify: the only channel with no holiday surcharge

Shopify is not a marketplace, and that is the whole story. There is no commission on your sales and no Black Friday surcharge. You pay your subscription and your payment-processing rate, and both are the same in November as they are in February.

Shopify Payments charges 2.5% to 2.9% plus $0.30 per online card sale, depending on your plan — Basic at 2.9%, Grow at 2.7%, Advanced at 2.5%. Plans run $29 a month for Basic, $89 for Grow, and $359 for Advanced when billed annually (see our breakdown of Shopify’s 2026 pricing increase). The cross-channel fee comparison in this guide is built on Webgility’s 2026 BFCM fee breakdown, which tracks all three platforms’ holiday rates side by side. If you use a third-party payment gateway instead of Shopify Payments, add Shopify’s additional fee of 0.6% to 2% depending on plan — one more reason most sellers stay on Shopify Payments through the holidays.

Two things do change for Shopify sellers in November, and neither is a fee. First, Shopify changed how Analytics measures sessions on September 21, 2026, so year-over-year comparisons of sessions are unreliable — compare orders, sales, and customer counts instead, which were not affected. Second, Shopify’s October 2026 updates actually help with Black Friday prep: discount testing in Rollouts (schedule and test a discount before it goes live), batch fulfillment for up to 250 orders at a time, and a new Canvas store designer. If you run a Shopify store, the October update worth acting on is the tax change: since October 23, return shipping fees are taxed automatically for US stores on Shopify Tax — review any manual workaround you built before the holiday returns start on December 26.

Shopify’s scale tells you why the weekend matters: merchants sold $14.6 billion over BFCM 2025, up 27% on the year before, with sales peaking at $5.1 million a minute at 12:01 p.m. Eastern on Black Friday. Your store does not need a share of $14.6 billion. It needs its own traffic to convert — and its own fees to stay low.

Amazon: the peak fee, the surcharge, and the storage trap

Amazon is where the fee stack gets expensive, because three separate charges hit the same order.

Referral fee: 8–15% of the sale price in most categories. This is the big one, and it is charged on the total price the customer pays, including the discounted price. A $40 product in a 15% category costs you $6.00 in referral fees before anything is picked, packed, or shipped.

Holiday peak fulfillment fee: about $0.32 per unit on average, on top of the normal fulfillment fee, for units shipped October 15, 2026 through January 14, 2027. For a large standard item of 8 to 12 ounces priced $10 to $50, the fulfillment fee is $4.20 off-peak and $4.48 during the peak window. A small standard item of 2 ounces or less goes from $3.32 to $3.51. The increase matches last year’s average — Amazon did not raise the peak this year, which is the one piece of good news. Full tier-by-tier peak rates are tracked in 595 Agency’s 2026 FBA peak fee guide.

Fuel and logistics surcharge: 3.5% on top of the fulfillment fee, added April 17, 2026, with no published end date. That 8-to-12-ounce item at $4.48 becomes about $4.64 once the surcharge is applied. Amazon calls the surcharge temporary. It has now been in place for seven months.

Storage: $2.40 per cubic foot, October through December, versus $0.78 the rest of the year. Standard-size storage more than triples. Oversize goes from $0.56 to $1.40. And the aged-inventory surcharge now starts at 181 days instead of 271, assessed on the 15th of each month — a removal or disposal order submitted by 11:59 p.m. Pacific on the 14th avoids that month’s charge.

Add the deal fees if you run one: Amazon charges $100 plus 1.5% of sales for a Lightning Deal or similar promotion during the holidays. That is easy to forget when you are calculating whether a deal is worth it — the fee is charged whether or not the deal performs.

The storage trap is the one that quietly eats Black Friday profit. Sellers who shipped inventory into FBA in September to be ready for the holidays are paying the $2.40 rate on every cubic foot from October 1, whether the units sell on Black Friday or sit until January. If your product is bulky and slow-moving, three months of peak storage can cost more than the peak fulfillment fee on the units that do sell.

Walmart: cheaper than Amazon, with its own Q4 storage jump

Walmart Marketplace charges no monthly subscription fee — that alone makes it the cheapest marketplace to list on — and referral fees of 6% to 15% in most categories, with payment processing included. For a seller already paying Amazon’s $39.99 monthly Professional plan, Walmart’s zero monthly fee is a real saving before a single order ships.

Fulfillment through Walmart Fulfillment Services starts at $3.45 per unit for items of 1 pound or less, and self-fulfilled sellers avoid that charge entirely. The Q4 catch is storage: WFS storage triples to $2.25 per cubic foot, versus $0.75, for units held over 30 days in Q4. The 30-day qualifier matters — inventory that turns over quickly avoids the worst of it, while slow stock gets expensive fast.

Walmart’s Black Friday exposure is smaller than Amazon’s in one important way: there is no per-unit peak fulfillment surcharge. The referral fee and the storage increase are the two levers, and both are easier to model than Amazon’s four-part stack.

The worked example: 100 orders of a $40 product

Fee tables are abstract. Here is what one Black Friday weekend actually costs on each channel, for the same product, the same price, and the same 100 orders — $4,000 in revenue. Assumptions: a $40 product in a 15% referral category on Amazon and Walmart, a large standard 8-to-12-ounce item on FBA, Shopify Basic at 2.9% plus $0.30, and no deal fees.

The gap between Shopify and Amazon is $929 on $4,000 of revenue. That is not a rounding error. It is the price of Amazon’s traffic, its fulfillment network, and its conversion rate — and for many sellers it is worth paying, because Amazon brings buyers Shopify never will. But it is a price you should be paying deliberately, with the number in front of you, not discovering it in a January payout report.

Two honest caveats on the Shopify column. First, Shopify’s $0 fulfillment line assumes you fulfill yourself or through a 3PL you pay separately — those costs are real, they just do not appear on a Shopify invoice. A 3PL charging $4 to $5 per order wipes out most of Shopify’s advantage. Second, Shopify does not bring you traffic. The $929 you save on fees is money you will likely spend on ads, email, or content to get the same 100 orders. The comparison is not “Shopify is cheaper.” It is “Shopify’s costs are costs you control; Amazon’s are costs you accept.”

Now run the discount math, because Black Friday is a discount event. At 20% off, that $40 product sells for $32, and 100 orders bring in $3,200 instead of $4,000. The referral fee drops with the price — 15% of $32 is $4.80, not $6.00 — but the fulfillment fee does not. Amazon still charges $4.64 per unit to ship a $32 item. The fee stack as a percentage of revenue rises every time you cut the price, which is why deep discounts on low-priced items are where Amazon sellers lose money fastest. A 30% discount on a $15 item in a 15% referral category leaves almost nothing after the $3.51 peak fulfillment fee, the surcharge, and the referral fee. Before you set a discount, run the price through the fee stack at the discounted price, not the list price.

The shipping deadlines you need on your site today

Fees are only half the Black Friday problem. The other half is promising a delivery date you cannot hit. USPS has published its 2026 holiday deadlines for the contiguous US: December 17 for Ground Advantage, December 18 for Priority Mail, and December 19 for Priority Mail Express. International parcels need to ship by December 9. FedEx has published its dates as well; UPS had not published theirs when this guide was written in mid-November — check before you print anything.

Put those dates on your store now, not on December 15. The announcement bar, the product page near the Add to Cart button, the cart, and your shipping policy should all carry the same cut-off dates, and the dates should include your own packing time. A customer who orders on December 18 expecting Christmas delivery because your site said “ships in 1–2 days” is a refund and a bad review waiting to happen. Shopify’s estimated delivery dates feature adds your fulfillment time to carrier transit time at checkout — turn it on if you have not already, and test it with a real order before Black Friday.

For Amazon sellers, the inbound cutoffs already passed or are passing: October 14 for Amazon Warehousing and Distribution, October 21 for minimal FBA splits, and October 28 for optimized splits. If your Black Friday inventory is not in a fulfillment center by now, it is not arriving in time for the weekend — plan for Cyber Monday and the December weeks instead.

A pre-weekend checklist for each channel

Shopify sellers: freeze your theme and apps by the second week of November — no changes except emergency fixes after that. Set up discounts in Rollouts and test them before they go live. Run one full test order per market with a real card and refund it; it is the only test that exercises taxes, duties, and the payment gateway together. Put the revert date for every sale price in your calendar, because a sale price stays until you change it back. And remember the returns window: return rules in Settings, Policies apply only to future orders, so a longer holiday window has to be in place before the first sale order.

Amazon sellers: check every SKU’s peak fulfillment fee in Seller Central — the averages in this guide are not your rates. Pull slow-moving inventory out before the aged-inventory surcharge hits on the 15th. If you run a deal, add the $100 plus 1.5% deal fee to your margin math before you commit. And remember the 2027 change: fulfillment fees rise $0.19 a unit on average from January 15, so January restock pricing needs the new numbers, not the peak ones.

Walmart sellers: audit which units have been in WFS storage for more than 30 days — those are the ones paying $2.25 per cubic foot. Price the referral fee by category, not by the 6–15% range; a 15% category at a 20% discount is a different business than a 6% category at full price. And if you self-fulfill, confirm your carrier cut-offs now, because Walmart’s delivery promises are enforced by the marketplace.

Every seller: set a theme, app, and integration freeze date and write it down where your team can see it. The most expensive Black Friday mistake is not a fee. It is a change made on November 26 that breaks checkout on November 27.

Frequently Asked Questions

What fees does Shopify charge sellers on Black Friday 2026?

Shopify charges no commission and no holiday surcharge. You pay your normal subscription ($29/month Basic, $89 Grow, $359 Advanced billed annually) and Shopify Payments processing of 2.5%–2.9% plus $0.30 per online card sale. Fulfillment is separate — self-fulfilled or through a 3PL you pay directly.

How much is Amazon’s holiday peak fulfillment fee in 2026?

Amazon’s peak fulfillment fee adds about $0.32 per unit on average, for units shipped October 15, 2026 through January 14, 2027, on top of normal fulfillment fees. A 3.5% fuel and logistics surcharge stacks on top. Standard-size storage also triples to $2.40 per cubic foot for October through December, versus $0.78 the rest of the year.

What are Walmart’s seller fees for Black Friday 2026?

Walmart Marketplace has no monthly fee and charges 6%–15% referral fees in most categories, with payment processing included. Walmart Fulfillment Services starts at $3.45 per unit for items of 1 pound or less, and WFS storage triples to $2.25 per cubic foot for units held over 30 days in Q4.

Which is cheapest for Black Friday: Shopify, Amazon, or Walmart?

On fees alone, Shopify is cheapest — about 4.4% of revenue in our worked example, versus 23.6% for Walmart and 27.6% for Amazon on 100 orders of a $40 product. But Shopify brings no traffic and no fulfillment, so the saving is often spent on ads and a 3PL. The right question is not which is cheapest, but which channel’s total cost — fees plus traffic plus fulfillment — leaves the most margin on your products.

When do Amazon’s peak fees end?

The holiday peak fulfillment fee ends January 14, 2027, and normal rates return January 15 — the same day Amazon’s 2027 fee changes take effect, raising fulfillment fees by an average of $0.19 per unit. Q4 storage rates end December 31, 2026.

What are the USPS holiday shipping deadlines for 2026?

For delivery by Christmas in the contiguous US: December 17 for Ground Advantage, December 18 for Priority Mail, and December 19 for Priority Mail Express. International parcels must ship by December 9. Add your own packing time to every date before you publish them.
