1. 2026 Fee-by-Fee Comparison: Amazon FBA vs. Walmart WFS
For years, US private-label brands treated Walmart Marketplace as an afterthought. In 2026, with Amazon's complex inbound placement fees, low-inventory-level penalties, and crowded $3.50+ PPC clicks, cross-listing existing FBA inventory into Walmart Fulfillment Services (WFS) has become the highest-ROI expansion play for 7-figure sellers.

2. How to Use Amazon's 10% Brand Referral Bonus to Beat the 15% Fee
If you are a Brand Registered seller on Amazon US, you don't have to accept a flat 15% referral fee on external traffic. Whenever you run TikTok ads, Meta ads, or creator affiliate links (via Levanta or Amazon Creator Connections) using an Amazon Attribution tag, Amazon credits you back an average of 10% of the sale price.
This effectively drops your Amazon referral fee from 15% down to 5%—giving you Shopify-like platform fees while keeping Prime 1-day conversion rates!
