Cost to reflash GM PCM computers is $200 including the return USPS priority mail shipping.  Most customers just put payment in with the computer with all vehicle details on the custom tuning form but some customers prefer credit card payments which I no longer do locally.  So I put a simple paypal payment option on this page to send me that $200 through the paypal system.  You don’t have to have a paypal account to send the money through their system.  I just had to have one to receive it.  Anyway they have a lot more money to spend on security for that sort of transaction than I do and I have used paypal for years with very little issue.
