One of the East Coast’s largest record shops, Princeton Record Exchange sells used and new CDs, DVDs, video games, and records. In business since 1980, the sprawling store has a catalogue of over 140,000 items, more than a third of which cost under $5. In addition to old finds, you can also peruse a large selection of new releases at discounted prices. The inventory changes daily, but you’ll always see the classics. For music, that means the Beatles, Metallica, Pete Seeger, Beethoven, Charlie Parker, Motown, and more. If you’re interested in selling your wares, call the store or check out its online buying guide; you can trade them for store credit or cash.
