This is a rather strange argument. Let's start with the second part. As it happens, shows are often sold out in advance and, gee, signs and stuff will say "sold out" for whatever day or shows have, in fact, been sold out for!!!
Now, to the first part. Yep, it is their word to say "sold". And a really good word since they are merely saying orders planned for delivery on those specific days are, in fact, "sold". But somehow you object to THEIR words and manage to twist them to mean "shipped". But that isn't their word, is it?
In fact, a basic understanding of the calendar would make that clear. Let's look at the calendar you posted which shows the week of September 18th as "selling now". Do you think they have a time machine and traveled into the future to that date to sell??? Of course not. They are referring to expected ship dates and are taking orders in July to ship in September.
This is just common sense. Now, you could complain that prior estimated dates were not met and maybe these won't be either. But to act like saying "sold" is essentially synonymous with "shipped" is kinda nuts.
