A great deal if you want plain "yellow box" Cheerios:
They are part of the $1.99/box General Mills sale this week at Meijer.
So, use the 50c/1 "Original Yellow Box Cheerios" from the 6/27 Smart Source insert in your sunday paper, which should double at Meijer, and enjoy an 18 oz box of Cheerios for only 99c after coupon!
I am already well stocked, and therefore I didn't buy extra papers this week (especially since the rest of the coupons didn't impress me much) but I will use two coupons to get two boxes this week for 99c. It's definitely worth stockpiling at that price.
