Goodwill has a website that auctions stuff from Goodwill's across the country. https://www.shopgoodwill.com
This place has everything from bearskin rugs to diamond rings. Their clothing and winter sports selection is hilariously great too; full of ski sticks, snowboard boots (actually ski boots), ski boats, helicopter ski goggles, and much more!
But really, they have some good finds on there in pretty much every category for cheap prices. People tend to go ape shit for big brands like Northface and Patagonia, but I've seen plenty pricier less known brands not even sell for $10. Lots of cool cheap paintings too. If anyone is into retro ski outerwear, they've had some good one piece ski suits recently.
