No, actually,
DVC would not benefit necessarily from setting things up this way. Typically, the price would be listed and then a credit listed against the purchase price. Typically, this means that the full purchase price would be used as the basis for taxes on the transaction as opposed to a situation where they actually reduced the price. It is like the consumer rebate on a car--you pay the taxes on the full amount and the rebate is subtracted at the end to determine the amount due. BTW, just got an email for an incentive on SSR add ons, too.
