Marketplace fee changes arrive in scattered announcement posts, take effect while you're busy packing orders, and then become impossible to look up. This page remembers them — platform, date, what changed, who it hit — with a last-verified date on every entry. Filter by platform below.
Last full verification pass: August 2026. Entries are compiled from platform announcements and official rate pages at the dates shown; platforms occasionally revise terms regionally — their current published terms are always the authority.
