I had a $100 off $500 offer on this card that expired tomorrow, June 30 (from AMEX; I believe it was specific to the luxury hotel brands). I hadn't used the $300 hotel credit. Yesterday, I drove to Ritz Laguna Niguel as I knew they carried gift cards in their gift shop. I have bought successfully there before and knew they would code as a hotel purchase. The rebates stacked and I already have $400 credit on my $500 purchase.
