American Express has an offer today for up to 75,000 Membership Rewards points on their Amex Business Gold Rewards card when you spend $5,000 in 3 months (the typical offer is for 25,000 points after $2,000). I saw the ad below when I went to sign into Yahoo.
You’ll earn 3X points on airfare and 2X points on gas. It’s free the first year, and $175 after. I don’t think it’s worth keeping around, but if you get the 75k offer, I’d jump on it (I’ve gotten it in the past, so I’m no longer eligible).
To see if you’ll receive 25k, 50k or 75k, you’ll need to go to this link, then fill out some information about your business (or “business”, as the case may be). Given that they’re asking for your address, I would guess that you’ll be receiving some mail from them and they’ll be selling your info. I put in a fake business and address to see what it would do, and I received the 25k offer. Eh.
