I just went over to Walgreens and holy clearance! Their back to school items were 90% off. We grabbed binders and a new back pack. The binders were .20¢ each and the backpack was only .99¢!
They also had summer items on clearance for 90% off as well! Make sure to head to your local Walgreens and see what they have marked down! It changes from day to day. I was there yesterday and no clearance and today all of a sudden there is a ton of Halloween stuff and all the summer/back to school stuff is 90% off!
