Amazon.com today announced a special promotion for its new shoe and handbag store: a negative $5 for overnight shipping on all orders placed through the end of February.

The online retailer opened Endless.com in early January, marking its first stand-alone U.S. retail site started from scratch.

Already, the site includes the unique (and expensive) feature of free overnight shipping on all its 250 brands and 15,000 styles for men, women and children.

But a negative five? Let's hope its coffers are as endless as its selection.
