What is the best way to track the sale of exclusive toy story items?

The only verified data we have concerns the existence of the Toy Story franchise and general information about Barbie films. No source in the evidence discusses sales tracking, inventory systems, or exclusive merchandise for Toy Story. Consequently, we cannot recommend any specific method or tool for tracking such sales. If you need guidance, you should consult industry resources or official Toy Story merchandise partners. The provided evidence does not contain the necessary details for a definitive answer.
