There was a deal some time back on columbiahouse.com. When you signed up, they sent you five DVDs for $25 with no obligation to buy anything else. While many people signed up and promptly canceled, I kept my membership (since I don't have to buy anything). Their prices are especially good for recent releases and then they offer additional discounts when you buy more than one. They send you a package in the mail each month with recent releases and deals. I recommend at least checking them out.
