Our client has requested that we add a final confirmation screen in checkout process that appears after the payment screen. This would seem a pretty simple addition, but having tried unsuccessfully to add one I found this in the Expresso Store docs.
'To give the user a choice between payment methods, you can either use the payment_method="" parameter, or submit a payment_method field on the last page of your checkout.'
Which suggests that payment HAS to occur on the last page of checkout wether or not the 'next' parameter is set on the store tag.
Has anyone managed to get a final screen working? If its not possible it would certainly be a useful option in future versions.
