I really could understand it if it were truly BASIC buttercream cakes, in fact I am thinking of trying this myself, but ONLY with a 10" 8" 6" cake truly basic decor, stacked, all components totally disposable. They can pickup if waiver signed or I'll deliver within a 10 mile round trip $1 extra per mile over. Cake tops extra. No modifications other than color selection allowed. Then if they don't like any of the $99 designs then we can start talking custom turkey!
Edited to add: I will only have 4 selections of designs available, no fillings except BC, 2 flavors (vanilla or chocolate) to choose from, and entire cake must be same flavor. Really bargain basement cakes. I mean if a bride is truly strapped for cash and doesn't care she will choose from the limited selection, if she wants more then she has to choose from the normal priced selections or custom design.
This is kind of like the car dealers who advertise the $7999 Kia Rio but it has no AC, no radio, and is a manual transmission. Most people (especially here in Texas) won't actually purchase that $7999 car, they will add the AC (another $1200), add the radio (another $300), want auto transmission (another $2000), so after it is all said & done they are actually paying $11499 for the car. Samething with cakes...offer the very low line bargain basement, no frills cake. Most want more so there go the upcharges.
