not at all, its simply to prevent a user from paying for the same item twice, they may
get the following
store one - �35 paynow
store two - �23 paynow
When they make a successful payment a http request gets sent from paypal, worldpay etc
which updates my db with the payment info, but unitl they refresh their page, there is
no way of them knowing so to prevent them paying twice to the same vendor, i need to
disable the button/form.
but please explain your comment :-)
cheers for the info
