Blockbuster Online has a large selection of new and pre-owned DVDs that you can buy. (You don’t have to be a member to buy, but if you are, you do get a discount of 5-10% extra off.) Use online coupon code augappreciation for $10 off a $10 purchase. (Thinking about becoming a member? Here’s a special sale link I found Try Blockbuster Free for Two Weeks, then plans as low as $3.99 per month. )

If you select only pre owned movies, you get free standard shipping! The discount will show before you need to confirm your order. This code is valid until August 31st. (Thanks Wisebread!)
