Which toy story characters are sold in disney world gift shops?

The provided sources describe Buzz Lightyear as a fictional character in the Toy Story franchise and give background about his creation and role in the films. However, neither source contains any information about merchandise availability, including whether Buzz Lightyear or any other Toy Story characters are sold at Disney World gift shops. Because the evidence does not mention Disney World retail offerings, we cannot determine which characters are available for purchase there.
