When this originally was done - the vinyl was offered well past the May 14 cut off date. It was sold in the store long past that, leading me to believe at the time that a quantity had been pressed for sale...and not just the preorder numbers were pressed. Looks like they didn't sell out, as this one popping up again shows.
With the fan club subs it's probably hit or miss. They have to judge how many copies they will need to get them through a years worth of people subscribing. U22, From the Ground Up, and North And South were all offered again in later years as a plus to the fan club gift or instead of. I'm willing to bet things only become limited in years when you have a lot of people subscribing for ticket offers, and the years in between are leaner...
