GoKawiilNewsletter details how Amazon's seller fees inflate prices across online retailers
The newsletter Not-Ship reports that Amazon's combined fees—referral commissions, fulfillment charges and advertising costs—can take nearly half of a seller's sale price, even though its base commission of about 15% matches eBay and Walmart. It notes these fee structures are central to the US Federal Trade Commission's pending antitrust case against Amazon.
GoKawiil's interpretation of the reporting above, not reported fact.
If sellers must raise prices across all platforms to cover Amazon's fees, that could explain why prices stay elevated even on competing sites, the newsletter suggests. This dynamic may be a key piece of evidence in the FTC's antitrust case, which argues Amazon's marketplace practices harm competition and consumers broadly.
- Amazon's total seller fees can approach 50% of a sale, despite a base referral rate similar to competitors.
- Extra costs like fulfillment and advertising are technically optional but effectively necessary for sellers to stay competitive.
- The fee structure is reportedly central to the FTC's upcoming antitrust lawsuit against Amazon.
