Hi, for $30 you can buy 1 or 10 valid cards depending on their cost in the CC store. You will also need a resident proxy for the cardholder's geo for work. You need to find a proxy service that sells proxies individually (for example, for $0.5-$1).
You can read about the easy method in this topic: "The best and fastest way to cash out an CC is by carding from card to card".
P.S. There are many other simple and quick methods, for this, study other topics on this forum and ask questions about each of them until you find a suitable and convenient method for yourself.
