How about Bundles?

[metafarion]

Support for URLs of the type itch.io/b/etc-etc-etc would be super useful!
I'm not actually sure what makes them different than the /s or /c URLs, but I didn't have any luck modifying the PATTERNS regexes to scrape them, so there must be something I'm missing.

This script is specifically meant for claiming games that are free on Itch, and bundles are typically paid, so I'm not sure I see the point of what you're asking. If you could provide a more specific explanation of what you're proposing, the functionality shouldn't be too difficult to add.
