Check online auction listings. Sellers on major auction sites have lots of competition, so they offer low prices for DVDs. For example, a new copy of "Toy Story 3" sold for as little as $5 on eBay in April 2011 (including shipping), while a new copy in a major retail chain sold for $15.
Visit pawn shops. Consumers who are strapped for cash or just want to unload excess belongings bring their items to pawn shops, who resell the merchandise for profit. If you're willing to buy a used DVD, you may find one for $2.50 or less.
Review online classifieds. Sites like Craigslist offer another avenue for used DVD sales. Sellers may group a certain genre of films or shows together, with prices as low as $1 each.
Stop by thrift stores. These stores often raise funds for nonprofit organizations by selling donated goods at reasonable prices. Not only can you buy DVDs here, but you'll also have the satisfaction of knowing you helped a good cause.
Scour yard sale tables. Buyers can find bargains on used DVDs at garage sales. If you arrive near the sale's closing time, sellers may be especially willing to negotiate their prices.
