How recently did this happen?
Originally,
DVC was very strict about the banking deadlines and would not allow members to bank beyond the deadline when making add-on purchases. Basically, if you purchased the add-on during the last 2 months of the Use Year, they would not allow them to be banked. That policy was relexed a few years ago where members have been allowed to bank points right up to the end of their Use Year with add-on points. This is one of those changes that has had little discussion, but does benefit members greatly.
MS has always allowed transferred points to be banked beyong the deadline - and I agree 100% that it's unfair that a member could not bank points acquired in a purchase thru DVC yet the transferree could bank the same points.
I can't recall when the policy was changed about banking add-on purchases, but it has been in place for a number of years now - even prior to the 2006 "enhancement" of the banking deadlines where we could only bank up to 25% of our point total up thru the end of the 10th month of our Ue Year but now can bank 100% thru 8 months.
