I'm right behind you AGS, I'm looking forward to the discounts from the Cheesecake shop lol. I've got a good friend who could have had his card for a few years now, and I have been nagging him for years to get it so I can score some cheap Cheesecake, but he's to bleeding vain lol
He's more concerned about people knowing how old he is than tucking into some cheap Cheesecake lol
