How much does a shower caddy usually cost?

The answer to this? It depends. If you are looking for a cheaper shower caddy, you should expect to pay between $15 and $50, depending on where you purchase the caddy and the material from which it is constructed. For a bigger, fancier, or different type of caddy (perhaps one constructed of metal, versus plastic, for instance, or one that is heavier duty) you should expect to pay more.
