I just opened it. Mine is #518. Those mini playfields look really cool. Make sure to hold on to the postcard, guys. You'll probably be able to sell it on eBay in ten years for $800.
Out of curiosity, how are you guys making your next payment? The letter said that they are still accepting credit cards, but it sounds like they would prefer a check. I was hoping to use a credit card so I can get the miles. Now I'm not sure what to do.
