Used them for the 1st time (08/2024). Didn't read their terms. Seller & items were just fine--can't complain about the transaction. BUT, did read more about Mercari and their fees and who pays for all of them (what they changed recently). I'll continue with Amazon , Ebay and some of the other on-line independent sellers. I'm paying a percentage of the sales price to Mercari plus all the other add-on's--FORGET IT. I guess it was my fault for not buying until I knew more of them, lesson learned. BUT I just assumed they worked like all the others and was totally wrong.
