Here is the deal...Walgreens has Purex Detergent on sale (not sure for how long) Buy 1, Get 1 Free.  If you save your coupons, the Red Plum coupon circular that came in the February 21st newspaper has a Buy 1 Get 1 Free coupon that expires 3/6.  So, depending on how nice the cashier is, each coupon could cover a different detergent and you could get 2 free.  I did read on-line of at least one family that was lucky enough to get them free.  If you try it, let us know how it went!
