Sandy, I am not familiar with Costco, but I had a note from Amy's
Kitchen that suggested buying their frozen food products from my local
retail stores, in case quantity (usually 20, and most will give 10 %
discounts for case buying). I am dealing with Meijer and Kroger Plus,
but have not yet tried this. Susan, OH
