So just so i am clear for me and for all those that come after me who might be a bit confused. PowerStore does not work for Australian websites who want to receive via credit card payment - being that Express won't work and you can't use Paypal Standard? Do you see this changing any time soon? ie being able to use Paypal Standard with Powerstore?
Okey doke, if that being the case, i need to go back to ECART and use standard. I'll look into the IPN thing and try to work that one out (though i might be back with a confused look on my face!).
