Depop sux

As someone who loves to thrift, I can't can't find many sites. I know of a few, mostly popular ones like depop, poshmark, and thredup, but are there any others that are at least somewhat active? I just like a LOT of y2k stuff and I'm really not too picky, but it's hard when a lot of things simply don't fit me so I'm unable to buy anything even after an hour of searching. Does anyone know of any good thrift sites? I already look in thrift stores as much as I can but it's hard with currently no car. I'm holding out hope that there are some sites out there I haven't heard of, but worse case I'll stick with depop and make a facebook maybe >~<
