Update: There is no current sign up bonus for the American Express Business Gold Rewards Card.
TPG reader Ted sends in an awesome deal: 75,000 American Express Membership Rewards points for opening the Business Rewards Gold card and spending $10,000 within the first four months. Application link which appears only valid for applications received on February 29, 2012.
This card currently has a 0 point public sign-up bonus and even when it first launched in August it was 50,000, but they did run another one-day only 75,000 point promotion in November that many TPG readers were able to take advantage of.
This card earns triple points on airfare, double points on gasoline at U.S. stand-alone gas stations, double points at U.S. stand-alone supermarkets, and single points on other purchases. The T&C state that you need to apply by today using Bonus ID A2AA, but there is nowhere on the application to enter that promo code. However, if you go through the application I recommend taking a screen shot of your information with the 75,000 point sign-on bonus information along the right hand side of the screen just to be safe.
2 To be eligible to receive the bonus points, you must (1) apply for the new Business Gold Rewards Card from American Express OPEN using Bonus ID A2AA prior to termination of this offer, but in no event later than February 29, 2012, and (2) charge $10,000 of eligible purchases on the Business Gold Rewards Card in the first 120 days of Card membership. The bonus points will be credited to your Membership Rewards® account 6-8 weeks after you have met the purchase requirement. Offer limited to 75,000 bonus points per Card account. Existing American Express OPEN Gold Card members are not eligible for this offer. This is a limited time offer, which may be terminated by American Express at any time. Offer may not be combined with any other promotional offers. Membership Rewards program terms and conditions apply.
