With the economy in (how shall we put this delicately?) the crapper, we have a feeling that even good ol' Saint Nick will be pulling on his purse strings this year. We can see it now: Mr. Clause opens our Christmas list, takes one look at the picture of Louboutins we printed off the Saks website, and reaches for the coal. Not so fast, Father Christmas! We've been researching designer goods for a discount, and there are enough tag-slashing sites on the web to stuff our stockings and save. Like Bluefly.com, where everything from Black Halo cocktail dresses to Levi's skinny jeans to Hermes totes are up to 80 percent off!
