I noticed that when I logged into my AMEX account, there was an offer for $50 credit back with a $100 purchase at Fleming's Steakhouse. $100 must be spent in the restaurant and not online. Expires at the end of May. Some have reported this can also be loaded via AMEX's Facebook Sync app.
Good news, thx OP and also yuyak for the gc info. Added the offer to my Costco AMEX in the iOS app. Can only add one card though. The terms don't seem to exclude gift cards or alcohol. Hot deal, green for you guys!
