After numerous comments (thank you!) I am convinced that this cereal deal at Hy-Vee is a good one:) Many of the commenters have been paying under $4 for 6 boxes of cereal and then getting FREE Milk on top of that!
Buy 6 boxes of select General Mills cereal (prices are ranging from 2.49-$4.49/box) and get $10 off your total and then a coupon for FREE Milk! You can use various $1/2 coupons from recent inserts and even .75/1 Total cereal printable here to make sure you get the best deal!
See the rest of Hy-vee weekly deals here and don't forget about the 6 hour sale!
