BWP (Buy with Prime)

Amazon & D2C glossary · Harpy Media

Buy with Prime (BWP) puts Prime on YOUR website: shoppers on your D2C store check out with their Prime account and get Amazon-grade delivery — fast shipping, easy returns — fulfilled from your FBA inventory. Amazon’s trust infrastructure, wearing your brand’s clothes.

What is BWP?

It sits at the intersection of the two pressures every Amazon brand feels: the need to build direct revenue (margin, data, email list) and the reality that conversion off-Amazon droops without the Prime trust signal. BWP imports the signal — and keeps the customer relationship yours.

What it changes on your site

The conversion lift: Prime members checking out on an unfamiliar site is friction (“who are you, when does it ship, how do returns work”) — the Prime badge answers all three at a glance, and merchants running BWP report meaningful checkout conversion improvements, especially with first-time visitors. The fulfilment economics: orders ship from FBA stock (MCF-style, at MCF-style rates) — one inventory pool serving both store and marketplace. The relationship: unlike marketplace sales, the customer account, email, and repeat-relationship live on YOUR site — the asset Amazon sales never hand over.

The strategic considerations

Fees: BWP charges per order (fulfilment at Multi-Channel rates plus a service fee) — model against your site’s current payment + shipping costs honestly; the conversion lift has to clear the spread. Brand control: the checkout experience is Prime-flavored but lives on your domain — your pixel, your analytics, your email capture around it. Inventory: BWP draws on FBA stock, so your D2C promotions now consume marketplace inventory — set aside or forecast for the second channel deliberately. The pattern that works: BWP as the trust layer on a site that ALSO builds owned marketing (email, content) around the traffic it converts.

In practice

A brand adds BWP to its Shopify store: checkout conversion rises 30%+ on Prime-member sessions (measured via their analytics), first-purchase customers get captured into the brand’s email flow at signup, and fulfillment runs from the same FBA pool as marketplace orders — no split warehouse, no double forecast. Six months in, the D2C channel’s margin on BWP orders beats marketplace economics even after the fees — and the email list it builds compounds independently.

⚠️ Watch out. A brand bolts BWP onto a neglected site — slow theme, no content, no email capture — and expects the badge to do the selling. Prime converts trust, not emptiness: the traffic bounces on the same broken page, now with faster shipping on the few orders that happen. The fix was never the checkout button; it was the store around it.

💡 Harpy tip. If you run both FBA and a D2C site, BWP is the cheapest conversion upgrade available for the site — but pair it with email capture and content so the trust Amazon lends becomes equity you keep.
