A general magic shop caters professionally to magicians selling many illusions. Most magic shops sell Rope Tricks and balloon tricks and card tricks... which are just a few which the majority of amateurs can perform well without much difficulty. The performance itself is what makes the difference.

There is often a learning curve when you're trying to learn about card tricks. It seems that some people have been doing it for so many years that they immediately know how to perform every card trick perfectly. If you're just starting out then easy card tricks are for you.
