No, we do not pre-authorize any transaction. This is something we do not support at the moment. We suggest you negotiate with the seller or affiliate a PPS on the upgrade to minimize your risk. At the end of the day, the outcome will be the same for your partners (decline pre-auths = pay on upgrades)
