All carts have bugs but I’ve never experienced a cart system with a bug fix turnaround as fast as CS-Cart or a forum so responsive. Let me also say that I have not experienced many of the issues that get posted which leads me to believe that many of the problems are user errors and not the cart system.
As for you question “I may have to add an option to a decal that will raise the price. I read somewhere where this wasn’t available. Am I Correct?” No, you are not correct.
