Here's a post from Britt on their forum:
Apologies for the delay. Not something we are accustom to either. Simply put, volume of business and the number of builders we have. Not anyone can build clubs for us and we are working on adding staff to help. Our guys are working as much as they can to get the clubs out as fast as possible without compromising any quality. We are quoting 10-15 days production time right now. We have been maintaining that time frame. We have in the past been able to get customs out in 3-5 days, but right now that is not possible. I know it doesn’t matter, but we are still much faster than OEM customs. We are the victim of our own success, I guess.
We sincerely appreciate your patience, and support.
