Amazon’s Multi-Channel Fulfillment, or MCF, has quietly become a performance marketing tool. The logistics service picks, packs and ships orders placed outside Amazon, drawing on the same inventory that serves Amazon.com. The big shift came on September 24, 2026, when US merchants gained the ability to show a Prime badge and offer Prime delivery in their own checkout at no cost beyond standard MCF rates.
That matters because a faster delivery promise is not just a shipping feature. Google added an “Amazon MCF” shipping policy to Merchant Center in October 2024, so delivery estimates flow into Shopping ads automatically. Google’s own June 2024 data found 1.5% to 7.6% more clicks and 1.9% to 7.2% more conversions for merchants offering free delivery in three days or less.
“We saw a 55.9% increase in conversion rate,” Andrew Curtis, chief digital officer of headphone maker JLab, said in an Amazon case study. TikTok has also leaned in: its ad platform added Buy with Prime checkout in August 2025.
One inventory pool, many channels
MCF orders move like FBA orders: goods enter Amazon’s fulfillment network, and the same unit can be sold on Amazon or dispatched for a Walmart Marketplace, TikTok Shop, Shopify or eBay order. Businesses without an Amazon selling account can register for MCF alone, according to Amazon’s German-language site from March 2026. Standard delivery is promised in three business days, Expedited in two, as of September 2026, and returns processing starts at $3.22 per unit.
Sellers can key orders into Seller Central or use connectors such as the Shopify app, Pipe17, Rithum, WebBee and CedCommerce. Amazon ships in unbranded packaging by default.
What the 2026 numbers look like
- US rate card dated June 1, 2026: a small standard item of 4 ounces or less costs $7.34 alone at Standard speed, $4.98 per unit in a two-unit order, and $3.64 per unit for four or more.
- Fees rose by an average of $0.30 per unit for 2026, with orders of three or more standard-size units unchanged.
- A 3.5% fuel and logistics surcharge has applied since May 2, 2026.
- MCF 2026 Preferred Pricing launched January 15, offering up to 15% off outbound fees and up to $1 of FBA credit per MCF unit, with credits capped at 50,000 units over six months.
Amazon has also priced MCF to win other channels’ orders: in July it offered 35% off Standard and Expedited MCF fees on TikTok Shop orders for 12 months, and on September 24 it announced a new Preferred Pricing Program saving 15% to 25% for six months. Single-unit orders remain the expensive edge. For a one-pound Walmart order, fulfillment providers’ analysis put MCF at about $8.50 against $3.45 through Walmart’s own service, according to an integration vendor rather than either retailer.
Marketing gains and data trade-offs
Amazon says US sellers using both MCF and FBA cut out-of-stock rates by an average of 19% and improved inventory turnover by 12%; neither figure is independently verified. For performance marketers, that means a TikTok or Google campaign drawing on shared inventory is less likely to leave your Amazon listing starved.
The trade-off is visibility. Routing a Walmart or Shopify order through MCF gives Amazon the buyer’s address and basket from a competing channel. Amazon says Seller Central tools launched in September keep off-Amazon data from informing its retail business decisions, but that is a company commitment, not an audited finding. The FTC already challenged the link between Prime and Amazon logistics in its September 2023 FBA lawsuit.
Packaging is another loss: unbranded boxes mean the carton cannot carry your logo, inserts or brand story. And channel rules keep moving; TikTok Shop’s January 2026 signal that independent Seller Shipping would end left sellers guessing about MCF qualification.
