Currently there is a coupon circulating for $2.00 off Honey Bunches of Oats when you buy a gallon of milk. This has been found on the doors where the milk is stored at the grocery (I found mine at Safeway). There is a little Safeway logo on the coupon but I asked someone that works there and was informed that it is a manufacturer's coupon -- this means it can be used anywhere.
I was at Walgreen's tonight (where I usually get my milk) and I noticed the Honey Bunches of Oats cereal was on sale for $1.99/box!
Buy 1 gallon of milk - price varies ($2.89 here -- it just went up)
Buy 1 box of Honey Bunches of Oats - $1.99
Use MQ - $2.00 off
...price of milk (in my situation, $2.89 for a gallon of milk and box of Honey Bunches of Oats!)
