Get 75,000 Membership Rewards points with Amex Business Gold Rewards card

(expires today) American Express offers 75,000 Membership Rewards points for signing up for their Business Rewards Gold card after spending $10,000 in 4 months with the first year's $175 fee waived. Usually this card comes with no bonus points, so this is a great offer if you are looking to spend a lot in the next few months (or willing to prepay expenses). As I wrote earlier, this card is good for spending on airfare (3 points per $ spent), but I don't think the perk is worth the $175 annual fee unless you fly a lot for business.
