I would think it'd be almost impossible to track, given that a lot of products change their pricing plan names, add new pricing plans, don't disclose prices, discount pricing based on usage, discount prices based on annual/monthly, etc. It's just not standardized enough to track, unlike tracking the price of a specific item in an online store, or even AWS instance prices.
