" Some people do shopping as often as they can. But you are especially crazy for shoping and you never save money." The first sentence is saying that many people shop (go buy things) whenever they can, whenever they have time, or as frequently as possible. The second sentence says that you are 'mentally strange', in other word wrong, to be shopping because you spend too much money instead of saving, conserving, it. I hope that answered your question. It was a bit hard to understand.
