I’m glad I held off on that deal on the Amazon Moto X4 with Special Offers I noticed the other day. Today, Google’s just announced its own Moto X4 Black Friday offer: $100 in Project Fi credit with the purchase and activation of an Android One Moto X direct from Project Fi. The credit is awarded 30 days after purchase and activation, and requires you use it with Project Fi’s service (at least for long enough to use up the $100 in credit). (Incidentally, if you’re not a Project Fi member yet, and you sign up with this referral link, you and I will both pick up $20 in credit.)

This is a pretty good offer all around. Google treats the Android One flavor of the Moto X4 as if it was one of its own Nexus phones—first dibs on operating system updates, full compatibility with Project Fi, and so forth. The phone is unlocked, so if you should decide to move it to some other service later that won’t be a problem. And last but not least, Amazon won’t be commandeering the lock screen to show its own special offers—something I’d been prepared to accept as a necessary evil to save a C-note, but now I won’t have to.

Project Fi is a great service for people who don’t need a huge amount of data–it’s just $20 per month, plus $10 per gigabyte, and they credit you back for any data you don’t use. Both David Rothman and I use and are happy with it. You can also add on a $5 per month device protection service when you buy your phone direct from Google.

So, while there may still be some doubt in certain circles as to whether other versions of the Moto X4 are fully compatible with Project Fi, Google’s Black Friday offer allows you to save $100 and avoid all that uncertainty by getting a phone that you can be sure will work with the service. The only down side is that it’s going to take about a week for them to ship it out to me. But I’ve gotten by without my phone for most of the month; I’ll get by for another week or so.

Meanwhile, if you don’t have or don’t want Project Fi, or would to prefer to save your $100 up front, that $299 Amazon version is still a pretty good offer.
