I generally don't pay more than an average of $5-$10 on each record depending on how rare it is. Most think they are gold plated, and price accordingly. I only buy rock LPs though, and most that i buy are bootlegs only limited runs and dont really have a market for (kind of).
Check the most popular names as they are the ones that go the most usually. Look for local record shops and bring them in...most buy used records to resell. Ebay is okay too.
