I believe that the $6.00 discount is for current members adding on at the 50 point level.
If Disney is still offering this to new buyers, I think that they pay the full price for a contract that low.
IMO, I don't think this info is listed because it was never something that was really touted to new buyers this past summer. I think if someone mentioned wanting to get in with less points, they were allowing it, but I didn't seem like they were officially changing the minimum as many posted here that they were not told about it before they asked.
Best bet is to call a guide and get up to date information as things change all the time.
