ISO: Sergachev Home Jersey

Hey Mammoth fans! Massive win today hope that propels us to a Wild Card berth. I'm wondering if anyone can point me in the right direction to buy a stitched Sergachev black jersey in my size (52/54) with the patches? I've been to six games this year each time arriving at least an hour early and every time without fail they have been sold out somehow of only that size. I'm a bit frustrated because I bought a ticket to todays game literally to buy the jersey but it wasn't there. Can't complain because it was a great game but I'm hoping theres an easier way to secure one especially since some of the store workers were saying they might not restock this season. Thanks in advance!
