Based on what I've been told, stores here don't approach hasbro for exclusives. Hasbro has to 'beg' the stores to take on exclusives in this country, and its only when the brand is doing well (at its most profitable to stores) that stores take on exclusives.
US stores are the ones who solicit exclusives to get kids and collectors into their store over their rival's.
The stores here though, have no interest in accommodating or targeting collectors (TRU would be an exception - not for getting the product, but in the promoting of it by being the only store to approach us to advertise TF toys). Any other store that had the slightest interest in collectors in this country, would promote that intention and products to the collector communities (like here and other AUS fansites, and at the collector fairs).
