A quick reminder that today is the last day to register your Amex card (any Amex-issued Amex) to received double rewards when you shop at World Duty Free.
You will receive double points for all spending up until 2nd December. (Or possibly 31st December – after you register, the ‘Thank You’ screen quotes 31st as the end date, not the 2nd ….)
(EDIT: The £5 voucher you are offered no longer seems to be working. However, you can download an identical ‘£5 off at World Duty Free’ voucher at http://www.worlddutyfree.com/amex6 )
