My SPG lifetime platinum kit arrived from FedEx! I earned my status about 3 months ago. My accomplishment was confirmed on the website, but the kit took a little while to ship. It had some standard SPG copy on platinum status along with two cool items.
1) A map of all my credited stays. Stays paid with points before those counted to elite status are not included. Still cool to look around the globe at my past 10 years.
2) A metal SPG membership card.
