Watch out for the low feedback bidders they are usually shills that run the price up. Private identity auctions I recommend staying away from as its always good to see feedback of who is bidding price up . The higher the bidders positive feedback is the better. Also look at how many other items the bidder has bid on. Shill bidders most of the time have 100% of their bidding on one auction or only one sellers item.
Added to my Watchlist! Couple follow up questions. Can you still book Worldmark resorts even as a resale? Read something on the members directory that made me unsure. How much does it cost to carry over points if you don't use it that year? Can you keep carrying them over or does it stop after 1 year?
