Record-Low Referral Bonus: Refer the AMEX Amazon Business Card and Get Only $25 per Person

AMEX referral bonuses are usually pretty generous, with offers as high as 20,000 Membership Rewards, worth about $320. However, AMEX has recently launched an unusually low referral bonus: if you refer the AMEX Amazon Business card, you can earn only a $25 referral bonus.

• Introduction to Credit Card Refer-a-Friend Programs

This card used to be unavailable for refer-a-friend, and later AMEX would open it up from time to time. On top of that, other cards also cannot refer to this card, which makes it a rather unusual case. Still, the $225 welcome bonus is pretty decent.
