(Thx Points Guy)
Today and tomorrow (August 8-9) American Express has increased the bonus on their Premier Rewards Gold Business card to 75,000 points after you spend $10,000 in 120 days (apply here). First year fee is waived, and it’s $175 thereafter. You can’t get the card if you’ve had an Amex business card (Green, Gold or Platinum) in the last 12 months.
You’ll earn 3x points on airfare; and 2X points on advertising, gas and shipping.
I don’t think it’s a card worth keeping around after the free year is up, but it’s certainly worth it for the 75,000 points (assuming you can hit that rather high spend threshold).
