Part of what makes marketplaces so appealing is the details they take care of like sales tax and security certs and fraud prevention and protections. I still have my etsy although, it is currently down to 1 listing because I was letting them all expire. I do have a shop on Micheal's MakerPlace that still has some jewelry listed. I can resurrect either of those, the problem is neither of them was every that successful but at least I would have to file sales tax. The question then becomes which one should the .com point to and sadly I'm leaning towards the etsy just because it has the longer sales history and reviews. 😏
I am currently considering a stand-alone through Square simply because I already have a square account and they offer a "free" website plan.
