Price Chopper has Cascade dishwasher detergent 1.29l or 1.7kg for $2 from May 23 to 29. There are $1 off coupons in the brandsaver valid on any Cascade product. That would make these only $1 each.

Also in the brandsaver, there are coupons to get free Cascade 2in1 actionpacs with any cascade gel or Powder purchase, so this would be the best time to redeem those coupons. For 42 you will get Cascade powder or gel and 2in1 actionpacs.

If you are lucky, you can use both of these coupons at the same time and get Cascade for $1 and also get free actionpacs. I know some people are successful in using 2 coupons,as you are using 2 coupons for 2 dif products, but i never tried it though.
