Valve add an easy way to see all the bundles a Steam game is in

Lots of developers like to team up for their games to put them in bundles, so Valve made it easier to see all bundles for each game on Steam.

As long as a game is in 3 or more bundles you'll now see a new link below the last bundle show on a Steam store page. Like the example below of "See all 7 bundles" for Balatro:

And when you click it, you'll be sent to a whole new bundle list page to present all the packages that include it. A pretty nice way to see if you can save some monies on various games together, perhaps you might find some more that interest you and end up buying a bundle this way. Steam bundles automatically adjust the price based on what you already have, and this page works the same - it's personal to you.

By default it will sort them by the most popular (by revenue for each bundle). Although you can change it to sort by price, discount, or alphabetical by name.

You can also just head direct to a bundle page for any game on Steam if you grab their app ID via: https://store.steampowered.com/bundlelist/*appid*
