The Rochester, MI store does NOT allow stacking. Not only do they not allow stacking but you are not allowed to use more than one coupon of any given kind. ie you have 3 Stoneyfield yogurts but you still are only allowed to use 1 q. Totally a lame policy! And I drove over an hour in one direction for that? There is one other about the same distrace or maybe a little further that I should inquire about.
