If you customized the bands, they should have shipped out by now. We arrive 3/21 and ours are already on their way and are expected to be delivered tomorrow (2/22) by the USPS.
If someone in your group wanted a grey band and you didn't enter the customization process for that particular person, the customization process is not 100% complete. If you did enter and select okay for everyone in your group, you should call the
MDE help desk to see why they have not shipped yet.
