I dislike amazon enough that ebay usually wins for weird items I don't have a place or time to find locally
anyone use shopgoodwill.com?
It's pretty good oftentimes, reminds me of early ebay, actually used stuff, good deals
they gouge the shit out of you on shipping though if you're not careful. You buy a kid's t-shirt for $3 and it's $15 shipping and handling. it's not bad depending on the item, but heavy stuff or cross country shipping is not often worth it.
Still I got some new helmets from there, seen good deals on race leathers etc, old videogames and cassette tapes and sunglasses, whatever
