REI Outlet offers the Timbuk2 Women's Lux Laptop Zip Pack in Black for $61.73 with free shipping. (Amazon charges the same.) That's $107 off and the lowest price we could find. This woman-specific fit backpack features a 13" padded laptop pocket, hood and rain flap, and multiple pockets.

Update: It's now out of stock at REI Outlet; however, Amazon still offers it for the same price.
