I found this at Publix:

On the top of the box of 13.75 oz. Idahoan Original Mashed Potatoes there is a REBATE form for the purchase price up to $2.39. It's dated 8/1/10-3/31/11. You will need your register receipt. Limit one per household. There is a orange and green "TRY ME FREE" on the front of the box. These are very good instant potatoes to me. Hope you can find this deal also.
