American Express is once again sending out mailers with Authorized User bonuses. Frequent Miler reports a bonus for the Premier Rewards Gold card, but there’s usually similar bonuses for other Amex cards as well. Besides mailers, these bonuses also show up online, but are still targeted. You need to have received the offer directly and it only applied to to targeted card.
Authorized User Bonus
Earn up to 20,000 Bonus Points: Each Additional Card Member added through this offer can earn you 5,000 bonus points after they spend $500 in purchases on their Card in their first 3 months. Limit of 4 bonus offers. Additional Card Members must be added all at once. Offer ends August 31, 2018.
This is a great bonus and easy points if you are targeted and can add a few people to your account. But be aware that Amex has been freezing some Membership Rewards accounts after such bonuses recently. Let me know if you are targeted.
