the 'only 82 units in stock' is probably just a local webstore assigned count. You know, labels actually do stuff like selling their releases wholesale to distributors, or trading them with other labels for their releases so they can put more stuff in their webstore to sell for themselves at a greater than wholesale price, because you know, people aren't just going to buy eight copies of the EP....
well, except in this case, and the people who would do so are lame and therefore cripples.
