I just noticed in the office depot ad for the week, ends tomorrow sorry for the short notice, that if you spend $15 you get a FREE backpack AND lunchtote!! You can read about it here
Some of the school supply deals are
2 pocket folders, 3 prong folders, Office Depot 6″ protractor and pencil pouches are $.05 each
Office Depot Multipurpose paper $3.99
Im sure there are a few more deals, but those are the best ones I see!!
