Just got a box of this at Target and it had on the box, "Try FREE after mail-in rebate" on the box.
I used the BOGO coupon for Mini Wheats but I was able to get one box of regular Mini Wheats and one box of Fruit Mini Wheats for the deal. I tried the Fruit Mini Wheats and it tastes like little squares of Pop Tarts -- too sweet for me. My kids like it (of course.) I prefer regular Mini Wheats.
