All cakes are charged by the number of servings, design, fillings, cake flavors, and delivery. The more detail and time that goes into the design the higher the price is per slice. This is why its nice to set up a consult to go over all the details of your cake.
If you are wanting a tall tiered wedding cake without the price an option to look into would be having one tier be real cake (the one cut into) and the rest fake made of Styrofoam (with a deposit, which would be given back with return or Styrofoam); then you can have a sheet cake in the back to serve to your guests.
It is important to remember your budget. We will go over your options and find what best suits your needs. Most tiered wedding cakes must be delivered and assembled on site to prevent a cake mishap. Delivery charges will be applied.
