Known by regulars as PREX, this New Jersey institution offers an astounding selection of used CDs (under $9) and vinyl (generally under $5) alongside new releases. Located just steps from Princeton University, the store attracts a diverse clientele from students to serious collectors. Unlike many shops that have inflated vinyl prices during the current boom, PREX maintains accessible pricing that makes building a collection affordable. The shop buys and sells around 15,000 items weekly, ensuring constant turnover and fresh inventory for regular visitors.
