American Express is offering 75,000 reward points if you sign up for their Business Gold Rewards card here:
This is valid TODAY only!
This requires you to sign up for the card and spend $10,000 in the first 4 months. If you can manage this, the 75,000 points is worth at least $750 but can be easily worth over $1,000 if you redeem the points for flights.
Thanks for the great tip!
