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

Links on Head for Points may support the site by paying a commission.  See here for all partner links.

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.

    Presumably we just have to book by 30th June but can stay or fly after that?

  • Waribai says:

    With the Amex deal, I’m looking at a £200 hotel booking. Any chance do you think of splitting it across my card and my wife’s card to get £100 off?

    • JQ says:

      Not unless it’s £100 per night for 2 nights

      • Waribai says:

        No…it’s £200 per night but I thought they might split it if I phoned them up!

        • Lionel says:

          It might work as I don’t think there’s the slightest chance the Amex machine does anything but recognise a qualifying transaction over £100.

          x 2

  • Lionel says:

    Bought a £10 One4all giftcard (which already triggered my £5) but I have currently got a zero balance.

    Was planning to buy a £10 Amazon voucher.

    Apparently you need to wait 24 hours for the balance to show.

    • mark2 says:

      I bought two yesterday and 25 hours later they still don’t work.
      Will keep trying, and hold off on the other cards.

      • Lionel says:

        Bit odd but the PO is clearly beyond reproach etc

        Also the fact that their website doesn’t seem to mention 24 hrs wait before activation…

        Got my receipt in any case.

        • Lionel says:

          My £10 balance was there this morning.

          FAILED in buying a £10 Amazon giftcard.

          SUCCEEDED in buying a £9.01 giftcard.

          FAILED in buying a 98p giftcard.

          Still showing a 99p balance, not sure what the issue is. (I thought the 99p transaction charge would be applied to my £9.01 purchase but this does not seem to be the case.)

          • Lionel says:

            Very odd, after several failed transactions, now my 99p balance was fine to buy another giftcard.

            Reported elsewhere that you can phone up Amex and get supps manually added for the Post Office offer.

          • Rob says:

            Amazon puts a 99p temporary charge on your card as a fraud measure. After a week it will fall away.

          • Rob says:

            That works fine, I did it last year to empty the last £5 on a one4all.

  • Mark says:

    Be careful if you put the Post Office spend through as Contactless. I bought four One4All cards on Saturday, once as a Chip & Pin transaction and three as contactless.

    The contactless transactions haven’t registered even though they are now showing – the offer status is still showing as ‘saved to card’ not ‘redeemed’.

    Have asked Amex to investigate.

    • TimS says:

      I have had this same issue. I paid via contactless yesterday & the £5 credit hasn’t been acknowledged. Still showing as “Saved to card” on my Etihad Amex

    • Roger says:

      Me too, I think. I bought 4 on 4 different cards (and – probably unnecessarily – 4 different e-mail addresses and passwords 🙁 ). 2 credits have been made; 2 not (I waited for statements.)

      I need to claim for 2x retroactive credits. Did your claim work, and if so, is there an e-mail address to use? Thanks.

  • bob says:

    There’s not much VAT on food

    • Fenny says:

      Exactly! And nothing on any receipt to tell you how much it is.

      • TimS says:

        There is.

        The * after certain items on the receipt indicstes that those items are VATable.

        • Alan says:

          Although I don’t think it tells you what rate of VAT? (some items are at a reduced rate)

          Agree with earlier posters that for this sort of purchase it should be the whole sum that counts

  • Rob says:

    VAT is a pass-through. The company does not see it, in effect. To you, as a customer, it feels like real money because you cannot reclaim it. To a business person, it is a pure pass-through. You pay VAT to your suppliers, you charge it to your customers and you pay the difference to HMRC.

    • Fenny says:

      Or reclaim it, if most of your sales are out of the country. That nice Mr HMRC used to give us back £500K a month in VAT.

  • Polly says:

    Got 2 of them, and bought e gift cards via their own amazon link. Wouldn’t work through the amazon link in your site Rob, sorry! Think that’s the only way to buy amazon.
