Discogs is amazing. Virtually every second hand record store on the planet is on there, so you can search up virtually any CD that exists, buy it, and have it mailed to you in a few days. I buy so much stuff there.

I often wish there was a Discogs equivalent for DVDs, but there doesn't seem to be.

Discogs was amazing, its sadly now a shit show. I refuse to buy from it or add to its database any more.
