Jump on this offer if you've been meaning to apply for the American Express Business Rewards Gold card! For one day only (November 3, 2011), you will earn 75,000 bonus Membership Rewards points if you spend $10,000 within the first 5 months of cardmembership. The normal bonus offer on this card is 50,000 points. In addition the $175 annual fee is waived for the first year.
This card is the counterpart to the personal Premier Rewards Gold card, so the earn rates are similar, though on different types of categories. You earn 3x points per dollar spent on airfare, 2x points on advertising, gas, and shipping, and 1x points on everything else. Membership Rewards points, as always, can be transferred at a 1000:1000 ratio to a number of decent airlines, including Delta, British Airways, All Nippon Airways, Air Canada, etc.
If you just recently applied for the normal 50,000 points offer for the same card, you may be able to send a secure message asking for them to "bump the bonus" by citing this offer (Bonus ID 7616). Despite American Express recently cracking down on bumping the bonus using targeted offers, this appears to be a public offer so it's worth a shot.
The spend threshold on this offer is very high, and for that reason alone, I will probably pass. After all, I'm still working on the spend for my Citi Premier ThankYou card!
