Last year, when the pandemic started, I tried out Mercari. Worth checking out as an alternative to Ebay. I’ve sold over 200 items on there problem-free(knock on wood) and as long as you’re not near that 200/20k threshold, they don’t require your social. I sell anything that I’d consider tag sale worthy on there or that isn’t of high value until you build up some feedback. If anyone wants a referral link, message me.
I still use eBay over 3k feedback since 2001 but for things I need more exposure for and that I’d consider more valuable. The 20k/200 nowadays is kind of a joke because you can reach 5k of that in taxes and shipping costs collected. That was all created when the Patriot Act was passed.
Amazon still reigns as the best site for resale if you were buying solely to resell items because of the crazy exposure you get from them vs ebay, mercari, etc. you’ll generally get 50%-100% more, even after fees, than you would on those sites. The only thing I’ve noticed is that they’re making it harder to sell in specific categories if you haven’t already been.
