The problem is Paypal payments pro is not available in Ireland. Using Express checkout is only good if the customer has a paypal account. If the customer does not have a paypal account and does not want to set one up then he or she has no way of paying using their credit card directly. I can't use Authorize.Net either since one has to have an American Bank account and possibly some other restrictions also. I can most likely find alternatives to Authorize.Net here in Ireland ( eg. sagepay.com ) but would like to know if in your opinion it is a difficult or easy change to make within Powerstore3. Alternatively, is there any other gateway out there, which is available in Ireland, for which powerstore can be modified to use.
