is there a good place to sell used Woot Shirts?

earlyre thought this was worth mentioning said

cleaning up/out around the house, I’s sitting of a stash of about 90 Woot Shirts, all men’s 3x, some obviously have shrunken, and i’ve expanded… mostly wearing 4x now…
at the moment I’m washing them all, then Rolling, and going to seal up in large space bags, as I’m Not really ready to part with them, (I could loose weight…) but don’t need them hanging taking up space.

If I Do decide to sell some(heck there are a few I don’t think i’ve ever even worn…, is there a good place to sell them/sell them to?
for some reason I don’t wanna just give 'em to goodwill…
