15% is the referral rate for many categories, with a $0.30 minimum. Electronics is often 8%. Apparel is tiered. The $3.45 fulfillment figure is the US non-apparel small-standard 4–6 oz rate in the $10–$50 column on the card that started 15 January 2026. The fuel and logistics surcharge is 3.5% of the fulfillment fee from 17 April 2026. Monthly storage, inbound placement, returns, and ads are not in the $9.68.
