Yes, that’s right. Sainsbury’s!
For those with very long memories, Sainsbury’s used to award BA Miles and Air Miles before the contract switched to Tesco in 2002. You may have had one of these in your pocket a long time ago:
American Express has launched a new promotion offering double Membership Rewards points until December 31st when you shop at Sainsbury’s! Assuming you convert your MR points to Avios points, you will be receiving 2 per £1 spent instead of the usual 1 per £1.
You need to hold an American Express Platinum, Preferred Rewards Gold or Green charge card. You can also take part if you have a Platinum Cashback Amex, with which you will earn double cashback. There is nothing for BA, Nectar, SPG, Costco or Harrods Amex cardholders, unfortunately.
You MUST register for this promotion, by visiting this website.
The rules say that the bonus Membership Rewards points will post within 8 weeks of the transaction, so you may not receive the last of them until the end of February.
The rules also state that you must have had your card for 100 days when you register. This is a very odd rule and one that has been cropping up recently in Amex promotions. I have no idea what the point of it is, to be honest.
Spending at Sainsbury’s petrol stations does not count.
