Tried the Coupgon app today at Coop. Cashiers have no clue how to use it.It took about 15 minutes to check out, but they were nice about it and it worked out in the end.I think the best deal is 1.00 off alymer accents and they are on sale for 1.25 apiece, there is limit of 3 though, also the 1.00 off vegetable and fruit is great if you are buying small ticket produce. think i am going to enjoy this app once the cashiers get the hang of it!!
