Last year I had a problem getting my card, I renewed all of my families memberships online and a few weeks later 2 of 3 cards showed up of course the one that did not show up was mine. I sent off an email to members services saying that I had only received two of three membership cards and asked if they could send mine. Within a week a membership card arrived for my wife, she already had hers so another email and a week or two passes finally my card arrived.
It does seem that there new system has a few bugs.
