I decided to become a member with a small resale contract--50 points. My goal was to have points at BLT but I was not sure whether I wanted to buy in with the 160 minimum it would cost me to buy through Disney as a new member.
Once I was a member, I was able to add on points at BLT with a lower minimum level--only 25. As it turned out, I ended up so excited to be a member that I added on 130 points. However, I only had to pay $96.00 per point. New members must buy 200 points at BLT to get them for $96.00 per point.
So, buy starting small, and then adding on at Disney directly for the resort I really wanted, I saved closing costs for my add on and paid less per point than I would have as a new member.
The only drawback to buying several small contracts, especially through resale is that you will have closing costs. These can always be negotiated with the seller but need to be figured into the price you pay. For example, if you buy a 50 point contract at $70.00 per point, but then pay $350 in closing costs, your price per point is really $77.00.
Good luck!!!
