Last I was here, there weren't very many Xbox gamers, but I'll put this here just in case. Today, Xbox announced the Xbox Game Pass Ultimate. It's a subscription that basically bundles Xbox Live Gold and Xbox Game Pass into one. It includes Xbox Live, Game Pass, and Game Pass for PC (games you can play on Windows 10).
Right now, there is a deal for the first month of Ultimate Game Pass for $1, and right now it upgrades your current xbox live and game pass subscriptions to ultimate up to 36 months. So any current xbox live or game pass months left get upgraded to ultimate game pass, which is both in one. I'm guessing that this deal will only be available for the week of E3.
Let this sink in for a moment: this means that
you can buy up to 36 months of Xbox Live, then for only $1 upgrade it to both xbox live and xbox game pass. That can save up to $360 of xbox game pass. For just $1. (And yes, I've tested this and it 100% works)
This is best for anyone who knows they're still going to use Xbox Live for the next 3 years. Even if you weren't planning on getting game pass, it's literally $1 for 3 years of game pass. Act on this quickly cause it'll probably last for only this week or less.
Note: it adds the months you have left from both xbox live and game pass. To quote Xbox, "if you have 3 months of Xbox Live Gold and 3 months of Xbox Game Pass already on your account when you purchase your first month of Xbox Game Pass Ultimate, you will have a total of 7 months of Ultimate on your account before you need to renew your membership."
If any of this is unclear or you have questions, let me know. If you need evidence that I'm telling the truth, it's explained in the FAQ section at the bottom of

TL;DR $360 of xbox game pass for $1. See above for details.
