Might be a good idea and a sensible way to go, have you contacted the club and suggested it?
It would not please or work for everyone tho, I actually like to try stuff first for quality and fit, I don’t buy clothes direct on line.
I get the issue that not having any XL on the hanger for game one is not the best, but back to the issue of it being a business, your initial order is on projected sales, if that outstrips your actual sales for what ever reason then it’s a business decision of what you do, make any future pre order, or buy more for the shop but then risk having excess.
From a stock point of view always better to sell out than have stuff left, if that means we miss, that’s life.
