Well, they did last generation, certainly.
As far as the price though, if you buy the Xbox with financing, $25 per month for the S or $35 per month for the X, that price INCLUDES Xbox Live Ultimate.
So for $35 bucks a month, you're not only paying the principle on a lease-to-own console, you're basically getting Xbox Live Ultimate for free along the way too.
Honestly, if you can get the financing plan for an Xbox S or Xbox X in your area, you'd be silly not too. They're basically just throwing free shit at you and helping you fit it into your cash-flow.
