re: Pricing Cakes & getting told it's to expensive.. Sheesh!

Do you charge differently for wedding and party cakes? I am working on setting up my price structure, I’ve got my portfolio, and paid for a website and URL (or whatever it’s called, my fiancé is helping me with the technical aspect, thank goodness!) through iPage. I’m having a difficult time deciding on which chart to use, I think Wilton’s seems too small (in some cases) and earlenes I like and understand but she seems to have it set up to charge differently by cake (I’ve only used the free version). Maybe I should just create my own, measuring my pans. I’m just curious what you all do.
