Are toy story toys sold at disney stores exclusive?

Quick Answer
There is no verified evidence that Toy Story toys sold at Disney stores are exclusive.
Explanation
The available sources provide no information regarding the exclusivity of Toy Story merchandise at Disney stores. The only confirmed facts are that the Toy Story franchise includes characters such as Jessie, and that Disney–Pixar produces a range of related products. Disney stores routinely sell a variety of licensed toys from popular franchises, including those from Disney–Pixar, but the data do not indicate that any of those items are exclusive to the retail chain. While exclusives are sometimes offered by retailers, this claim has not been substantiated by reliable sources for Toy Story items.
Because the sources do not mention any special agreements or limited‑edition releases tied specifically to Disney stores, it is safest to treat the merchandise as generally available. If a customer seeks a particular Toy Story toy, checking the Disney Store website or visiting a location is a reliable method, but the lack of documented exclusivity means other retailers may also carry the same products.
In summary, based on the evidence at hand, there is no confirmation that Toy Story toys sold at Disney stores are exclusive. For definitive information, one would need to consult official Disney merchandise announcements or retailer disclosures that specifically state exclusivity arrangements.
