Best thing I can say to you is never, ever compare yourself to a grocery store chain. I was in charge of a Walmart bakery, and all the cakes are frozen and designs are pre designed. Your level of work should not be compared to a grocery store at all. Remember that you are making your own cake, icing, etc. You are doing unique designs, not just a cookie cutter cake you can get any where. You have a talent, so price accordingly. =)
