It's true! And amazing! And really easy! Just go to Albertson's and get a copy of their ad (usually in the front entryway, but if not just ask for one at the Customer Service desk). Buy $25 in participating items, and at the register it will print out a $5 Albertson's voucher and a Kraft rebate form. So you pay the $25 up front, but as long as you use the voucher (within two weeks) and submit the rebate, you get it all back! Let me know if you have any questions, or just ask an employee--they are generally really nice and helpful.
Fyi, the $5 Albertson's voucher is one per transaction, and the $20 Kraft rebate is one per household/address. (I did it twice, for me and my parents, so there's $50 worth of food shown in the pic, not $25.)
Yay for free food! :)
