I have a question...
I am new to OKlahoma and been working trying out different stores to see who has the best deals since apparently there is no Kroger stores here (I miss Kroger dearly!).
The only stores that double here in Oklahoma that I'm aware of are the Homeland stores which double up to $1 excluding soft drinks and a few other items (beer , cigs and coupons for free items, I think). They will only double one "like coupon" per transaction, which means that if you have 2 identical coupons they will only double the first one and give you face value for the other one. I've gotten a lot of FREE stuff from Homeland. They also will allow you to stack coupons but they don't offer Homeland coupons very often.
Super Target puts out a lot of their own coupons and will allow you to use them with manufacturer's coupons. If the regular Target carries the item you can stack coupons there too.
I'm really sorry you had problems at Crest...the one in Edmond is great! I get cheap and free stuff there often even though they don't double or accept IP coupons.
If you have a Homeland near you just check out the Homeland forum...the ad specials/deals are posted weekly on wed. (that's when the new ad starts). Also, I'd check here for deals at Crest... that way you don't have to make a trip there unless you see something you want posted here.
Welcome to Oklahoma...if we can do anything to help you don't hesitate to ask!
