I went to the grocery store yesterday and noticed the following:

The big-size Corn Chex has a BOGO FREE Old El Paso Taco seasoning mix cut-out coup on the back;

The big-size plain Cheerios has a pampers coupon cut-out on the back, not sure of amount but keep an eye out

And, the big-size Trix (which I bought) has the following cut outs, all exp 8/3/08:
$1/2 Pillsbury toaster strudel
$1/2 General Mills Kid Cereals
$1/2 Hamurger Helper Microwave Singles
$1/2 Any Flavor Hamburger, Chicken or Tuna Helper
$1/1 Fruity Cheerios Cereal
$1/2 4.5oz or lgr Bugles, Chex Mix, or Gardetto's snack mixes

It's cool because the Trix boxes (14.8oz) Have a huge blue banner accross the from that says 'Save $6 on Family Favorites, coupons on back".

OH i didnt realize there was a general Found Q's forum, mods you may like to move this there so more people can see it before they stop the promotion
