Stupid question... How do you "pay" for apps from the apps market?

[Roadblock]

Like the topic asks. Do they just go on your cellphone bill or do you have to pay via a credit card, PayPal etc?

I've not actually bought anything yet but there are a couple things I can't "find" via other sources and everything for the most parts pretty cheap so I figured I would just pay.

Thanks guys and girls!
