linnysue,
I saw that this old thread had been resurrected.Thought I'd just tell you what I did and it may or not be helpful. I monitored the WorldMark eBay auctions for several months and got a pretty good sense of the price ranges and general direction of prices. I also noticed that inexplicably there would at times be auctions for the same or very close to the same amount of points within days of each other that had a .10 to .15 per point difference. I was not always rationally able to explain the difference i.e. lower rated seller , fewer banked points etc. To this day I cannot really explain the difference in price in that sometimes occurs in similar point auctions within several days of each other. In any event, I establised a range in price per point that I was willing to pay and with the help of some information by some sniping specialist Tuggers on these boards, I used a sniping service to bid on a number of auctions. Finally, after at least several failed attempts, I ended up with the deal that started this thread. I kind of made buying a WorldMark membership a hobby for a little while so I did spend a fair amount of time researching and reviewing sales on eBay (my wife thought that I was a little nuts since I spent quite a bit of time on it).
So far I have been very happy with the purchase and my wife is slowly coming around to the idea that I'm perhaps not completely insane. In late January, We traded for a 2 bedroom unit at Coconut Beach Resort in Key West for a stay in March (March 7-March14) for 4,000 credits because we got it during II's flexchange period (59 days or less before check in ). We had an absolute ball at the resort and greatly enjoyed the people that we met there. The information on this board and on WMowners.com has been essential and I have spent many an evening enjoying the posts on this site. I have found this site to have an amazing collection of experts on not only timeshares but on a number of other topics as well (for example technology issues discussed in TUG lounge).
Hope this helps. There is some excellent information available here as well as some very nice and very smart people.
