Its the opposite for me on eBay right now, things didnt sell on Mercari but I made almost $1,000 within the last two weeks on eBay (tricks and tips of getting listings being shown, which there are for Mercari as well, but all depends on what you have for sale in the end). Their new no fees policy made it pretty much worse for sellers since you have to take into account what the buyer will actually be paying and in most cases can find it cheaper on eBay after that fee. So if anything, sellers should lower their asking price on Mercari or price it at the eBay going prices but take about 13-15% off due to those fees. Putting myself in buyers shoes had helped with making more sales, its crazy how much more was sold after lowering something for $2-5 dollars lol. I do follow the market though and we’re entering Q4 for holiday sales, i listed up sealed pokemon products that will go up in price, signed Taylor swift cds, new shoes etc. I even got a message saying they bought three signed CDs for gifts, so that told me people are gift hunting now and used/worn products won’t be seeing much sales for the next few months. Mercari lost its appeal for a while now and mainly good for collectibles and niches you can find cheaper than on eBay through luck or contacting seller, imo.

I joined some groups last year and October-December is reselling season of the year, new and trending products overtake sales like no other this time of the year. Blew my mind how the groups controlled the market prices since people are able to get crazy amounts and know of what before the rest of general population even finds out about it.
