We have just signed up for a merchant account with a company called Centipaid. This system of charging a subscription seamlessly fits into the website and the subscriber purchases an image called a centipix which has a subscribe code that works for a certain period of time. (there are different centipix you can purchase)

This system fits well as they collect the money and pay us, straight into our account, on a monthly basis. The only downside to this is that the purchase is in US dollars although I don't feel this is as big an issue as it was a year of so back

The set up should be complete at the weekend
