The exclusivity means that if another store wanted to carry it, they would have to purchase it for full retail price from Ookoodook., pay the shipping, and then resell it at a price point high enough to make a profit (retail+shipping+profit margin). Even accounting for buying multiple copies, for almost any amount they could order, it would be cheaper for the customer to just bypass them and order straight from Ookoodook. Aside from that, the profit margin would be so small that it wouldn't really be worth it to have any in stock.
