This is one of my favorite daily deals sites. Here and Totsy are some of the BIGGEST savings. Right now, they are offering a $10 credit to NEW signups, and shipping is free until Dec. 16th. There is a sale called "What Kids (Really) Want" and you can get this backpack or another for FREE, with free shipping.
I have personally used this site, and I know they ship fast and also, good news: No sales tax if you live in TX like there is at other sites! There are a number of free things right now, and sales change all day long, so check it out! It's amazing. The other day I got bath salts that cost $11 a pound, 3 pounds of them, for FREE!
