I'm just curious. Do you buy digital? If so, from where?
CDs? Used or new? Where, online or at a store?
Vinyl? New or used? Online, or at a store or local record shop?
Me, I buy a lot of digital stuff on bandcamp.com , a great place for indie artists. They have FLAC too!
For CDs, I download and listen with my Zune Pass and if I like it I buy them on Amazon, and I've bought a CD from eBay with good results (ripped well, but it had a Bonus DVD with one of those flip trays inside the jewel case and the teeth on the other side are messed up so the disc falls out easily, but whatever it's fine if I don't mess with it; everything else A-OK)
For vinyl, I buy some new vinyl on Amazon, sometimes random used records from a local record shop. A local artist I've come to be friends with personally sold me a big bin of records he had to sell for space, so with having to clean them that's gonna keep me busy for a long, long time.
Happy listening! :)
