NEW: Get 6,000 points when you add a free Amex Gold supplementary card

American Express has launched a special offer for anyone who holds the American Express Preferred Rewards Gold Credit Card and who has never added a free supplementary cardholder.

Until 21st May, the bonus for adding your first supplementary card is doubled to 6,000 Membership Rewards points.

There is no spend target to hit on the supplementary card.

The only bit of small print to note is that “bonus points will appear in at least two instalments of 3,000 and 3,000” points.

Your first supplementary card is free so this is a very easy pile of points.

This offer is only available on the FIRST supplementary card added to your American Express account. If you already have a supplementary card in issue, you will not get the bonus if you add another one to the same account.

You MUST use this page of the American Express website to apply.

Other cards also have supplementary card bonuses

Whilst no other card is running a special offer at the moment, the usual bonuses – as long as you apply via the link above – are available on other key American Express cards when you add your FIRST supplementary card:

• The Platinum Card – 5,000 Membership Rewards points
• The American Express Rewards Credit Card – 2,000 Membership Rewards points
• British Airways American Express – 1,000 Avios
• British Airways American Express Premium Plus – 3,000 Avios
• Marriott Bonvoy American Express – 3,000 Marriott Bonvoy points
• Nectar Credit Card – 3,000 Nectar points
• The Harrods American Express Card – 1,000 Harrods Rewards points
• Platinum Cashback / Platinum Cashback Everyday – £5

How long does the offer run?

The special offer on American Express Preferred Rewards Gold runs to 21st May.

If you have never issued a supplementary card in the past on your current Amex Gold card, now is as good a time as you will get.

You must use this special page of the American Express website to add your supplementary card. If you use any other page of the Amex website, your bonus will not track.
