Target retail stores offer the Mossimo Supply Co. Backpack in Green for $10.48. (It can also be ordered online, but you'll have to spend $25 or more to dodge the $4.99 shipping fee.) That's $20 off list and the best price we could find. This cotton canvas backpack features a front flap pocket, two side flap pockets, drawstring closure, and a turn-lock top flap.
