I'm in discussion stages with a woman who wants her wedding cake to have the bottom tier fake and the top two real. I'm planning on charging my normal rate for the top two tiers, but I have never had a request for a fake bottom tier. Would it be priced cheaper or should I charge per slice for the bottom as well? Thanks!

Charge the same as if it were a tier of real cake. Styro tiers are not cheap and the main cost is the time it takes you to decorate, which is not going to be less with a dummy tier.

I charge 80% of what the real cake would cost. Styro is about the same cost as cake and the icing/fondant is the same, decorating is the same, delivery is the same. The only difference is no torting, no filling and I can work ahead. Therefore 20% less.
