American Express has introduced a limited-time promotion offering substantially increased point bonuses for eligible cardholders when they add their first supplementary card, and the best part, these bonuses can double up with the increased sign up bonuses that we wrote about the other day!

What is a Supplementary Card?
A supplementary card is an additional card issued on your existing account for use by someone else, typically a family member or partner. The supplementary cardholder receives their own card with their name on it, but all spending appears on your statement and you remain fully responsible for all charges made on both cards. It's essentially a way of giving trusted individuals access to your account whilst maintaining a single billing arrangement and credit limit across all cards.
The first supplementary card carries no annual fee, making this promotion accessible to all new cardholders, for no additional cost. And, there is no minimum spending requirement on the supplementary cards to qualify for these bonuses.
What is the Full Offer?
The promotion is available to holders of the American Express Gold Card or The Platinum Card who have never previously added a supplementary cardholder to their account. The offer runs until 31st October.
Under this promotion:
Gold cardholders receive 9,000 Membership Rewards points (an increase from the standard 3,000 points)
Platinum cardholders receive 12,000 Membership Rewards points (an increase from the standard 5,000 points)

Doubling Up with the Welcome Offers
This supplementary card promotion operates concurrently with American Express's current welcome bonuses:
40,000 Membership Rewards points for new Gold card applications
80,000 Membership Rewards points for new Platinum card applications
Cardholders can combine both offers, potentially earning 49,000 points for the Gold, or 92,000 points for the Platinum card.
Get a referral code though for your new Gold or Platinum cards, and you could net 54,000 Points for the Gold, or an enormous 112,000 points for the Platinum card. If you don’t know anyone who has an Amex, and would still like a referral code, then email sam@pointswellmade.co.uk and we will sort you out!
Application Process
To qualify for the supplementary card bonus, cardholders must:
Complete their primary card application first
Add the supplementary card exclusively through American Express's designated webpage
Complete this process before the 31st October
Key Restrictions
Adding a supplementary card during the initial card application will disqualify applicants from receiving the bonus.
The offer applies only to the first supplementary card added to an account
Cardholders who have previously held supplementary cards are ineligible
The specific American Express webpage listed above must be used for the supplementary card application
So there you have it. Follow the steps above for your Amex supplementary card bonus, and you'll be on that dream trip in no time!
