It is definitely 50 (not lower)
They can/will only sell under 50 if it is an add on for a
DVC member-we were on the waiting list for BWV back in nov/dec and wound up finding a small resale contract while on the wait list-right before we closed on our resale DVC called and now had points avail-we had decided by that time we actually wanted 25 in addition to the 60 point resale contract we had purchased but they could not sell us less than 50 until we were officially members-so they held the 25 points for us (for 10-14 days) until we were officially members with a "master contract" that they could put them under. We were told they did not sell master contracts under 50 points (obviously this can be done via resale)
