An Advertising Question

Hi,

I’m planning to use SellSpace for my advertising, as it seems really simple to set up.

I also got a plugin though, for my sidebars, that allows a number of adverts to be placed on top of each other.

This plugin uses the default Banner advertising rather than the SellSpace medium, which leads to a pertinent question –

SellSpace is a doddle- a client comes along, pays for the ads, and it’s live straight away.

How does a client pay for ads using the Default Banner system?
