I do that too, come home and put it in an airtight container and throw out the bag. I will save the bags in the future too. I would have dug that bag out of the trash, put the food in a trash bag and taken them both back. Maybe you would have had better luck. I can't believe you spent that much and the store wouldn't do anything for you. That's just not right. So glad to hear the boys weren't harmed badly by the buggy food. That could have been much more serious.
