They claim that the same place that they make the authentic jerseys in Canada is where they'll make the Fanatics "authentics" when they take over. Now, I will be shocked if they make those quality versions easily available for the customer given how Fanatics generally does business, so I might just chalk it up to me being out of the game for a while. My wife and my wallet will probably thank me.
I would think you might be able to go to a pro shop or even a local tailor to get that patch stitched on right away. Not sure what rink is nearest to you, but they might have a way to do it for you if you ask them. I've lately just gone the route of bring my jerseys to Sports Minded Unlimited because they'll ship them to the place that supplies the Devils their jerseys if I'm not mistaken, so I know they'll always come out in good shape.
