When I did this a few years ago, it was 3000 minimum purchase required for 1 resale enrollment. When I was at the sales presentation, it was a required presentation as part of a Encore package. The price was around $14/point at that time. I ended up paying $9.99/point for the 3000 points, including closing costs. But also, that got me 6900 points, not just the 3000, since i was enrolling a week worth 3900 points.
The way it got down to the $9.99 is by them giving me a 20% discount, then they gave me some other discount related to a "special" offer they were running at the time, and also gave me all the money paid for the Encore towards the purchase. It's been a few years, so I don't recall all the specific numbers right now, other than the $9.99/point. We also financed to get an extra 3000 points as an incentive over a 2 year use period, after we paid 18 months of payments. Sure, we could have rented 3000 cheaper than the interest cost us, but it was just easier, and my wife was focusing on that as an incentive to buy, so we did it that way.
As for a recommendation, I would simply negotiate, if you don't like the price. I don't know how much they will move off of their current offerings and specials. But, during the presentation I mentioned above, I repeatedly told them we were not there to buy anything. I also referenced the ability to purchase resale points at a much cheaper rate. We did go into a discussion about how it would be advantageous if my resale week (3900 points) was also enrolled. I honestly think the sales guy just knew he was going to have to be at a price point that was more acceptable than anything close to their current retail price.
