How does your billing backend work, and do you store cc numbers?

Why do I ask?
I presume that if they are charging the customer extra, and keeping the profit, that they are charging the customers creditcard themselves, and then sending their own payment details to you to make the purchase from you.

The ony way they could get round this were if they charged the customers cc a small fee themselves, and then sent the cc number to you to charge the rest.
- and I hope that anybody would think this very suspicious if they saw this on their statement.

So, I can see 2 possible solutions to counter this.
If you store the cc numbers, then check to see if the same number is being used multiple times for the same product.
Check the customers address against the cardholders address to see if they're different.
