Thanks to Wendy for passing this info along about Family Dollar. Her Husband is the manager of one of the local stores. Hope this info helps answer some of your questions.
There are 2 in Boise, one each in Kuna, Nampa, Caldwell, Emmett, Homedale, Parma,Weiser,and Payette.(check website for other areas.) They just talked about coupons in the last meeting. They do stack coupons meaning- they take a store coupon and a manuf. coupon on the same item. But you have to have as many items as coupons.(10 coupons -10 items) And you can only use 15 coupons in one transaction. But as usual you can do multiple transactions. Hope this helps
