Donate: Goodwill Industries, Salvation Army, and others.

Sell: Used-CD shops or on-line.

Tips: Keep in mind that on eBay or Amazon, a run-of-the-mill CD rarely fetches more than $5. Factor in the site's charge to the seller and the hassle of mailing to the buyer and decide if it's worth your time. The CD Exchange (www.thecdexchange.com) offers an easier alternative: E-mail it a list of the CDs you want to sell (they should be in excellent condition, with liner notes) and the CD Exchange will respond within 24 hours, telling you up front what it will pay (in cash or merchandise credit). You mail the CD Exchange the discs, and it sends you a check. (The company has the Better Business Bureau Online seal of approval.)
