iDeal on Drupal 7 with commerce integration
In Drupal 6 we had übercart. Now we have commerce for Drupal 7 (well actually we have übercart for D7 too but that's a different story). In any case, commerce is the way to go. And for us in the Netherlands, iDeal is the way to pay online. Thanks to Bart Feenstra we already had an iDeal API module for 7 and now we have commerce integration! Hooray!
