Hey guys, I don't know if this is nationwide or not since I can't find it mentioned on the website, but I just got back from Kmart in Jefferson City, MO and they are doing Super Doubles from January 11th - January 17th. They will double manufacturers coupons up to and including $2.00. The sign said there is a 25-coupon limit.
Managed to save an extra $12 thanks to this! Every dollar counts nowadays.
There is also some advertised deals worth checking out. General Mills cereals are 5 for $10, with a $5 rebate. So you end up paying $1.00 per box -- an amazing deal for cereal!
