How do toy story toy prices change over time?

The only references supplied identify Toy Story as a franchise and list its characters. No pricing data, historical price trends, or market analysis are included in these sources. Consequently, there is no verifiable evidence to describe how Toy Story toys have been priced historically or how those prices have fluctuated. To learn about price changes, one would need to consult external sources such as toy retailer catalogs, auction sites, or collector forums that track used and collectible toy values. Without such data, it is not possible to answer the question based on the current evidence.
