Stealing from Reddit, for you risk takers
and
This is a Google doc that takes scraped Amazon Warehouse deals and sorts them by discount. I am unsure how often it updates (he has a website blocked by my work filter that has more details), but I did just get a couple in from this on pretty nice (35-40%) discount a week or so back and they came with minimal damage: one with minor corner bumps and one with a minor scratch.
Usual Amazon Warehouse rules apply: likely you'll grab some damage or an opened item, condition quality listed has little relevance to reality, small chance of a raccoon eating your record sleeve when it arrives, etc. I personally stop around 25% discount or so since the damage risk otherwise really isn't worth it, though I'm sure there's some record OOS everywhere else buried in there I'd like at 5% off. *shrug*
Edit: Just checked the Dealforager link on my phone, definitely more updated but I find it less friendly to look at. Some interesting items I don't normally see on a decent sale elsewhere include single copies of the 4 LP White Album, David Bowie's Blackstar (European), Jack Johnson's En Concert, At least ones I was considering.
