I don't think DVD should proactively discourage resales and feel that it's not what DVD is trying to do with these restrictions. The goal appears to encourage direct sales since DVD realizes (correctly, I might add) that a healthy resale market can be a good selling point. That's why DVD has been enhancing benefits for direct sales purchasers. I know it has been mentioned before (both in this thread and others), I don't think it's too far-fetched for DVD to eventually adopt a tier system where its "best" direct customers are awarded for their "loyalty." For now, even with an eligible direct contract in hand, why would an existing owner look to direct sales when it's time to add-on unless it's a small number of points or at a new resort?
However, if adding on the next contract directly through DVD brings on yet additional and perhaps even more enticing benefits (as the number of direct points grow), one might at least think twice before start looking at the resale market. Plus, if someone is already committed to buying, let's say, a 100-point contract direct (for whatever reasons), what a great motivator would it be if the next threshold of benefits is only 50 points away! Even if that prospective owner ends up buying only 100 points on the initial contract, he/she will surely look for a direct purchase should there be a need for additional 50 points down the road. This system inherently encourages/promotes direct sales for existing owners, who most currently no longer bother buying direct because they are already "set."
