Buy 4 General Mills cereals selected varieties 2 for $5 and get a coupon for a free gallon of Deans Milk up to $4 (does that mean any gallon of milk ?)

Pictured:

Cheerios 9.9 oz
Reeses Puffs 13 oz
Coco Puffs 11.8 oz

I'm getting this from an online copy of the sale paper. If anybody that has the actual copy sees a wrong amount please let me know so I can correct it. Some of the things are hard to read. Thanks!
