Maximise your Avios, air miles and hotel points

£5 off a £25 Amazon order TUESDAY ONLY – stacks with £25 Amex Membership Rewards code

Links on Head for Points may pay us an affiliate commission. A list of partners is here.

To celebrate being named Britain’s No 1 retailer for consumer satisfaction, Amazon is having a one day sale today. Long term readers may remember that they did a similar deal last year and the year before.

You will receive £5 off any order of £25 or more using the code BIGTHANKS.

Gift cards do not count, unfortunately. All items must be sold directly from Amazon and not from one of its partners.


The Amazon home page is here.  Full terms and conditions for the offer can be found there.

This should stack with the American Express Membership Rewards ‘£25 off a £40 purchase’ offer if you have Preferred Rewards Gold or Platinum Amex card.

This is for SOME PEOPLE – definitely not everyone – who link their Amex Gold or Amex Platinum card to their account and part-pays with Membership Rewards points.

This is what to do, assuming you have not done this offer in the past:

Link your Membership Rewards account with your Amazon account by visiting this page on the Amazon website 

Buy £40 of items on before 31st March (these MUST all be sold by Amazon and not third party merchants, and excludes digital content and gift cards)

IMPORTANT:  Items must be purchased in a single order and shipped at the same speed to a single address

You MUST select your Membership Rewards-earning Amex card as your payment card (you cannot use gift cards or any other payment source)

Part-pay for your order using Membership Rewards points.  The sneaky option is to redeem just 10 points for a 5p discount.  This saves you ‘wasting’ MR points on a low value redemption.  You will only get 0.45p per point and you shouldn’t waste more than 10 of your valuable points on such a poor deal!

Do NOT add the code at this point.  Click ‘Use This Payment Method’ and continue to the final payment screen.

Enter code AMEX25SWP at check out (the code must go in after you have selected part-payment with your Membership Rewards-registered card)

You should be able to do this after redeeming the BIGTHANKS code.

The offer expires at midnight tonight, Tuesday 19th March.

    The AMEX25OFFSWP didn’t work for me either and in a live chat she said it had ended as they had reached the 8,400 users. She did say that if you originally tried to apply for it when the code wasn’t working and had tried before the promotion was filled then it would work if you tried again. I guess you’ll only know if you were within the 8,400 if you try again and it works.

    sorry about dud info if £25 code has expired!

    • Rob says:

      Link is still up and in date.

        I’d like to test it for you but I already used the £25 off £40 on all our household Amazon a/cs!

        well, twice per account 🙂

        here’s a tip for others: all members of your household can get their own a/cs & this may prove useful in future same as it does with this promotion
