Yes, 2nd and Charles is a chain — but the bargain bin at the Broomfield branch is overflowing with CDs, most priced at about $1, which means that gems can be had for the cost of a single iTunes track. There are 2nd and Charles locations all over the country, and they all work the same way: Bring in your used CDs or DVDs, and a cashier will figure out their cash or store-credit value while you browse. Afterward, use your trade-in money wisely: While there are plenty of pricey items to choose from, including new CDs, DVDs and comic books, the bargain bin up front is a treasure trove.
