I'm guessing Paul put the color grey up on the site and then, once he visited this forum, decided the grey wasn't going to sell well. However, if anyone did actually order them, I'm betting AE had to tell them, "Sorry, you can't get this because demand is too low." I wonder if anyone ordered them.
Honestly, I was kind of wondering the same thing
Paul! Do a midnight navy Grayson! 😀
