If the store refuses, contact the company directly. Sometimes the store wont take it back but the company will. Or at least, give you coupons to try a different flavor. I wouldn't feel bad about that - because sometimes in ALL products there is a fluke bad bag, something that didnt get processed right - or maybe its just not something you like or maybe they just have a pee poor product Alot of companies treasure that feedback. Once they get so many complaints they will know they have to reassess that product and create something better. If noone told them it was icky they might not know, and then no better product would be made!
