Why would they send out a separate email promising to add points within a couple days of the transfer otherwise?
Why would they clearly write in the T&C that it wont stack?
"In the event of multiple Bonus Points transfer offers in market for the same offer period, eligible Members will be provided with the highest Bonus Points offer. For example, if a Member was eligible to be awarded 20% Bonus Points on an eligible transfer of points under a Membership Rewards offer, and the Member was also eligible to receive 10% bonus points on transfer, under a Qantas offer, the higher of the two offers will apply and the Member would receive a 20% Bonus Points on their eligible Points transfer. Members are not eligible for more than one offer on one transfer."
I am not complaining... I booked a few tickets with this bonus, plus a infant for $24... Thanks to
