Well shoot, I already have this card and just saw this thread.
Thanks for flagging it anyway and I look forward to finding out about the next offer.
I *am* going to get a different Chase card that will pay me 2% cash back on everything I charge, so I can use that when none of my cards offers any higher percentage of cash back. I forget the name of the card, but it gives you 1% when you charge something and the other 1% when you pay your bill.
