I also got the email and I have received ~650 QFF points so far. Should be >1,000 QFF points after yesterday's shopping.
Now this does not have anything to do with Qantas but when I went to get petrol in Sydney last week there was no way for the person at Woolworths petrol to determine what fuel offers I had on the Everyday Rewards card. He said to me it was all automatic with the oldest fuel offer used first. What if I have higher fuel savings with recent purchases but still have lower fuel offers with older purchases that are not expired how do I access the new offers?
In my experience in using 20c off vouchers through the liquor shop, the highest value 'voucher' goes to the top - so you use it first.
