What is a max buy price?

Do platforms charge fees on sales tax?
Some do. eBay, Depop, Facebook Marketplace shipped orders, Reverb's processing fee, Etsy's processing fee and Whatnot's processing fee are charged on a total that includes the buyer's sales tax. Mercari's and Poshmark's are not.
How current are these fees?
Each platform's fee rule was checked against its official fee page in October 2026 for US sellers in standard categories. Each calculator page links the source; check it before you price.
