Get £5 cashback on £10 Post Office spend with American Express

American Express has launched a new cashback deal in association with the Post Office – and a pretty generous one at that.
I wrote back in April about how the Post Office had begun to accept Amex cards. This offer is presumably part of that deal.
You can receive £5 cashback on your American Express card when you spend £10 at a Post Office before 29th July.
At the time of writing this deal is NOT on the cardmemberoffers.co.uk website. This means that you can only access it via the ‘Offers’ section of your online American Express statement. Only Amex-issued American Express cards (Gold, Platinum, BA, SPG, Nectar etc) will count.
You cannot register supplementary cards separately because the offer is only visible via the online Amex account of the main cardholder.
20,000 registrations will be accepted. Given that you have two months to make a £10 purchase, it would be sensible to register all of your applicable cards.
The obvious thing to purchase is £10 of stamps, but any purchase for which American Express is accepted at the Post Office will do the trick. Most Post Offices sell ‘One4all’ gift cards, usable in many High Street retailers, which is another possible option.
The main restriction is that online transactions and transactions made via a self-service machine in a Post Office branch do not count.
If you only have an Amex card issued by MBNA, Lloyds or TSB don’t be too concerned – there is a decent chance that this offer will eventually migrate to the cardmembersoffers.co.uk site.
