As good as BIAB is, their add-on is just as confusing. Or maybe it's just me who has trouble understanding it. I would appreciate it if someone could explain this to me:

I have the Audiophile 2025 version and am now planning to upgrade to 2026. I usually buy Xtra Styles, which usually costs $29 when purchased with the software. I thought that XPro Styles didn't add anything new, but I realize that it may be content that isn't included in Xtra Styles. I am even more confused by the fact that the purchase includes a Bonus PAK. But it is possible to upgrade to a 2026 49-PAK for $49.

What is the difference between Xtra Styles, XPro Styles, Bonus Pak, and 49-Pak?

Is there overlapping content, or is there new content in each add-on?
