Barnes & Noble has a great promotion where many (but not all) of their DVD Box Sets are "Buy 1 Get 1 Free" (buy two and the least expensive is $0). Plus, use 15% off one item coupon code V4K9A4G to reduce the price of the one you do get charged for. A best bet: the Grey's Anatomy Season 2 DVD Set is $59.99. Buy 2 of this (or something else) and get both for $59.99. Enter the 15% off code and that drops to $50.99, or $25.50 each, the best deal around by over $10. Plus, 3-day shipping is free on orders over $25.
