Agree with others that deals have been a little thin of late, with the same offers for the same drastically overpriced stores again and again.
That said, I used a $15 off $30 Samsclub.com offer just last month (January), and was rocking a 10% rebate on cellphone bills September through November. Both of those were on my Hilton Amex.
My other Amex, a Simply Cash Business card, has seen nothing of value since August, when I got $20 off $100 purchase at Texas de Brazil. Actually, I was able to triple-dip on that one; I got the same offer on my Simply Cash, on my Hilton card, and was able to add it to my PenFed Amex card via Twitter, an option which Amex has since taken away, sadly.
For offers like that, I've found that the most efficient method is to use the Amex card to buy the exact dollar value of gift cards to trigger the deal. That way I benefit from the deal any time I want, not boxed in by the deal expiration date. Also, I can put any spending above the required $ amount on whatever rewards card gives me the best cashback (which is almost never the AmEx card the deal is on). I got one of my best AmEx hauls on a Sam's Club offer like that; 20% off a Sam's Club purchase over a year ago. Bought $1,250 in Sam's Club cards (also redeemable at WalMart), got $250 cashback on my AmEx. Unfortunately, that was a deal I only got on a single AmEx card, and I've just finally exhausted all $1,250 in gift cards.
Right now the only deal in which I have even tepid interest is $20 off $75 at Boxed.com (on three cards). But I honestly don't know if I can find $55 of stuff worth buying at Boxed.com.
