You get what you pay for if you are wanting to tell everyone you have a Martha Stewart Wedding Cake. But they are not worth the price. It is sugar and flour, for crying out loud!
Get you some cake pans of various teer sizes. Bake a normal cake with a cake mix. For icing, use sugar and marshmallows melted in the microwave with water added until the mixture is smooth for icing the cake.
You can get the same smooth-looking cake results and you can do it yourself. Don't spend money on cake. Spend it on the honeymoon!
