I finally went to Cub so that I could check out what the deal was about. All you need to do is to buy 4 participating P&G prducts and $10 worth of school supplies on the same receipt and you get the $10 back.

I bought 4 pringles $1.09 each - .30 coupon and $10 worth of paper for the computer.

Rebate slips were near the school supplies for me. I think the was good only at select SuperValue stores. Doesn't expire until late Sept (do not have the forms in front of me).
