I noticed on my Steam Wishlist that a game was listed as $25.80 at a 41% discount.
But I had distinctly remembered seeing a much lower price previously and the 41% and ~$25 did not make sense to me.

I looked at the product page and found that the wishlist UI was being helpful by providing the absolute lowest price for the game at the present moment, which was part of a bundle. That is where the 41% discount was being calculated from and not the price of the base game.

This may not appear to be important enough of a business or UX concern, but I would prefer if the wishlist UI continued to show the lowest price for the product, including bundles, but with a bit more transparency like including a 'As part of a bundle' text element linking to the bundle, and for the base game price to used to calculate the discount.
