I use the obvious thrift and second hand stores when I’m out and about. When I look online the best site I’ve found is HamiltonBooks.com. I’ve also been checking out gruv.com, which I found when I went looking to preorder Deathstalker. I’m curious if there are any good sites I’m missing out on. I’ve been getting into UHDs but some of the prices seem outrageous.
I mostly find movies and shows at thrift stores. We go to different ones each week. Yesterday one of the stores had all the media on sale for $0.50 and some of it like VHS was $0.25. I ended up with about 30 items for $10.
Thrift stores are great, especially when trying to find oddities.
