Maybe true, difficult to say. But the grocery store analogy isn't as clearcut as that, IMO. At the grocery store, the milk can't be sold after the expiry date, true, but there are endless other milk options, and no real need for anyone to buy that milk from that store. If you don't get that particular milk jug, you can always get one somewhere else, tomorrow. Or today. Or drink water. The milk itself is also worth less, the closer it gets to the expiry date. Who wants to buy milk that shouldn't be drunk after today? When it comes to MLB help, there are a limited number of milk jugs available, multiple buyers with perceived need for the milk that can't be satisfied by drinking water, and a set date upon which, there is no longer milk available, of any kind at any price. In some cases (Boyd, for example), the milk doesn't even go bad after the expiry date, it's able to be used for the next two plus years by the seller. And even if it will go bad later (after the season is over), it doesn't lose it's usefulness on the expiration date.
