Their website says "6-inch and 8-inch cakes available online starting at $65."
I never thought to check websites before, but the pre-decorated (or standardly decorated, idk how to phrase it) cakes at Carlos Bakery are not as expensive as I thought they would be. $25-50 for a 7 inch cake. Cupcakes at $3.50. A 6" cheesecake for just under $17. (why? cheesecakes are fabulous! I would pay more for cheesecake than for a regular cake!)
