Saw this offer on the US site this AM and I came over the FT to post this but see that I'm scooped by a few hours!
The T&C's are not clear to me but the intent of the promotion seems to be that the additional 50% bonus is for NEW members - DM accounts that have never been registered with Points.com. I expect this excludes a lot of us after a few years of Grand Slams.
Has anyone that is an existing member of Points.com tried this? Please report back.
