How much does Buy with Prime cost merchants?

Amazon charges a Prime service fee of 3% of order value, excluding tax, with a $0.30 minimum per order. Fulfillment starts at $5.60 per unit, storage at $0.78 per cubic foot per month, and payment processing through Amazon Pay is 2.4% plus $0.30. There is no subscription fee.

Does Buy with Prime work with Shopify?

Merchants using the Shopify app pay Shopify's payment processing fees instead of Amazon Pay processing. Test it on a few products before turning it on store wide.

Do I need FBA to use Buy with Prime?

Many brands use the same stock they hold for FBA, so one inventory pool serves Amazon.com and their own site. Plan stock carefully so DTC orders do not cause Amazon stockouts.

Is Buy with Prime still available in 2026?

Yes. As of October 2026 Amazon still offers Buy with Prime under the same name and published updated 2026 fees, including a lower $0.30 minimum Prime service fee. Its site also lists newer features such as Reviews from Amazon and an API with early access sign-up.

Does Buy with Prime increase sales?

Amazon reports that brands saw an average 16% increase in revenue per visitor in its A/B testing of 167 merchants between July 2023 and June 2024. Results vary by product and price, so test it on top sellers and judge it by contribution margin after the fees.

What is Buy with Prime?

Buy with Prime puts Prime benefits on a site you own. A Prime member sees the Prime badge and delivery promise on your product page, checks out with the payment and address stored in their Amazon account, and gets the fast free delivery and returns they expect from Amazon. Amazon's site says it handles payment processing, storage, picking, packing, shipping, customer service for delivery and returns.

As of October 2026 the program is still called Buy with Prime. Amazon's site also describes it as offering Prime checkout and delivery on your site, and has added features such as Reviews from Amazon, which can show your Amazon product reviews on your own pages, and an API that is open for early access sign-ups.

How does Buy with Prime work?

Inventory is the starting point. Your products sit in Amazon's fulfillment network, and orders from your site are shipped through Amazon Multi-Channel Fulfillment, so one pool of stock can serve both Amazon.com and your store. Our Amazon FBA inventory management guide covers how to plan that stock.

Buy with Prime on Shopify

Amazon lists an Amazon MCF and Buy with Prime app for Shopify, which connects Shopify orders to Multi-Channel Fulfillment and adds Prime checkout.

Test the app with a few SKUs first and check that theme, discount codes and subscription apps behave as expected; our best Shopify apps guide covers what else to check in your stack.

Buy with Prime vs Seller Fulfilled Prime and your own 3PL

Seller Fulfilled Prime puts the Prime badge on your Amazon listings while you ship yourself; it does not touch your website. A 3PL ships DTC orders but cannot show the Prime badge. Buy with Prime is the only way to put Prime on your own site. See our Seller Fulfilled Prime guide and Shopify vs Amazon FBA comparison for the wider picture.
