I have an MBNA WorldPoints American Express card (used to be mastercard and they switched!) which I've had for many years. I recently received an e-mail inviting me to an event sponsored by Blufish Concierge. Has anyone heard of this? I'm sort of confused by it. The event sounds really nice but I am wondering if it's a gimmick. I'm wondering if I heard about it on flyertalk and signed up for it!
