Err. Even if it wasnt serversided, you cant edit values on the other guy's side.
Is it possible to, for instance, COD someone an item for 1 gold, and when they make the payment, before accepting, somehow edit the variable so it's like 100mil instead of 1 gold? or are the prices at which you set COD's and there payments serversided?
