Just ran across another backpack/lunch kit deal that I wanted to pass along. Right now at Toys R Us when you purchase a backpack you will get a lunch kit of your choice for FREE. It says you can order it and get FREE in store pick up if you like as well to save on shipping.
I found this above Ice Age backpack for $14.99 which seems to be the going price for most of their backpacks.With purchase of backpack I can then get this matching lunch box below (priced at $7.99) for FREE.
but my favorite that I think my daughter would like the most is the Angry Birds version.
