Did you just spend a ton of cash on new textbooks for school? Unless you're super talented and can balance all your books on your head or hold them in your muscular arms, you'll need something to carry them in between classes, and you'll probably want to get that something for less. That's where Zazzle comes in! All weekend long, you can get $15 off messenger bags with coupon code SCHOOLBAGS4U, and keep your hands free for texting your friends taking notes. Expires 08/12/2012.
