Get more £50 Shop Small credits adding American Express supplementary cards

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

As we covered yesterday, American Express is bringing back ‘Shop Small’ from next Monday – click for our full article.

Until 13th September, you will receive £5 cashback on the first 10 transactions you make for £10 or more at participating ‘Shop Small’ businesses.  That means a total cashback of £50.

Importantly, you can register supplementary cards separately and earn an additional £50 each on those.

This means it is a good day to talk about the benefits of adding a supplementary card to your American Express account and what bonuses you will earn if you do.

Why should you add a supplementary cardholder to your Amex account?

Reason 1 – you can double-up on ‘statement credit’ cashback deals

Many people do not know that the holder of a supplementary card can register it as a stand-alone card on the American Express website.

If my wife logs in to her Amex online account, for example, she can see her own Gold card as well as the supplementary card she has on my Platinum account.

Importantly, the supplementary card receives its own batch of statement credit offers.  This means that, if an offer appears on both your main card and the supplementary, you can usually (not always, but usually) register for it twice and earn it twice.  You can do this for the new round of ‘Shop Small’, opening up a potential £50 additional cashback and it will also work for other offers in the future.

Why you should add an American Express supplementary card

Reason 2 – it is easier to hit spending bonuses

By giving your partner a supplementary card on your American Express account, you can both focus your spending onto the same card.

This is especially useful if you are working towards a spend-based bonus, such as:

The 2-4-1 Avios redemption voucher on the British Airways American Express cards, which requires annual spending of £20,000 (free BA Amex) or £10,000 (the paid British Airways American Express Premium Plus)

The 10,000 bonus Membership Rewards points for spending £15,000 per year on American Express Preferred Rewards Gold 

It also makes it easier to trigger a sign-up bonus, such as the £3,000 of spending required on the British Airways American Express Premium Plus card to receive the 25,000 Avios bonus.

Why should you get a supplementary American Express card

Reason 3 – you can share card benefits with other people

If you have The Platinum Card from American Express, it is crazy not to use your one free Platinum supplementary card.  The person who gets it will receive:

a Priority Pass for airport lounge access

full travel insurance for themselves and their immediate family (now requires opt-in under new EU rules)

Hilton Honors Gold, Radisson Rewards Gold, MeliaRewards Gold, Shangri-La Golden Circle Jade and Marriott Bonvoy Gold hotel status

Eurostar lounge access etc etc

Even if you are single, you might want to issue a supplementary Platinum to a trusted friend or relative purely for the benefits.  My Mum had a supplementary Platinum on my account many years ago – I didn’t renew it when she hit 70 as the insurance no longer covered her – and my wife has one now.

You can issue further supplementary Platinum cards after the first free one for £275 each per year.  In the right circumstances this could be good value for the right person given the Priority Pass and hotel status card benefits.

Note that not all Amex cards give all of their benefits to supplementary cardholders, so check the small print.

Why should you give our supplementary American Express cards

Reason 4 – you get bonus Membership Rewards or Avios for issuing a supplementary card

American Express now has a dedicated page on its website which you can use for issuing supplementary cardsYou can find it here.

The bonus is only paid on the FIRST supplementary card issued.  You will receive:

3,000 Membership Rewards points for issuing your first Preferred Rewards Gold supplementary card

5,000 Membership Rewards points for issuing your first Platinum supplementary card

3,000 Avios for issuing your first BA Premium Plus supplementary card

1,000 Avios for issuing your first free BA Amex supplementary card

There is NO bonus on the Marriott Bonvoy or Nectar American Express cards.  There are bonuses on the two cashback cards.  The link for issuing supplementary cards is here.

Note that you WILL receive the bonus for issuing a supplementary card even if you did not qualify for a sign-up bonus when you originally applied for the card.


The new Summer 2020 round of ‘Shop Small’ gives you £50-worth of reasons to add a supplementary card to an existing American Express card.

As you can see above, however, there are other valuable benefits to giving out supplementary cards too.

    Posted in detail further above but post then blocked or moderated due to the http link to the shop small promotion.

    As indicated in detail there Amex have an IT problem with giving new customers with activated cards access to the Shop Small promotion and their computer sseem not to want to do until you have paid your first statement bill with them.

    It refuses to add to the my offers page even from the dedicated shop small page registration link when logged in to my online card services.

    I think it would be really great PR if you able to persuade Amex IT that they need to fix this IT problem.

    Many thanks.

    I applied for a suppl BAPP and got 3,000 bonus avios in my account today.
    I had another suppl cardholder years ago – I added him just to get the bonus then cancelled the card.
    The bonus worked again tho. Anyone with a similar experience. I mean, I’m not complaining- just curious to know if the truck would work again if I were to cancel the suppl card in the future etc

    I cancelled my Amex gold charge card in OCT 2018, I was planning to apply this year near Xmas so that I can get the welcome bonus points again as it’s been more than 24 months.

    If I get a supplementary card under my wife’s gold card account would this affect the bonus points when I apply? As the t&c are not clear when you held a supplementary card.
