I was at a Dollar Tree a couple days ago and they had a lot of Cars stuff - not toys, but "stuff." I got my daugther several different sets of pens/pencils, stickers, folders, erasers, and a couple other things that I'm drawing a blank on right now.
Wal-Mart also had folders on their school supply isle yesterday for .76. My daughter has to have folders for school and I tend to buy these because I have seen her classes folders and everyone buys the plain single color ones. I've watched the teacher trying to get them passed out at the end of the day and it can be a pain. I figure if my DD has the decorative ones, at least that's one less for the teacher to "think" about.
