Impulse Gaming and Maxlink4Gamers sell the Xbox One S in their shops. There's a Forza Horizon 4 bundle too.

For the controller issue, it's something annoying that I also have on my Xbox One X. I guess even the One S has it? Anyway, the issue is very specific in my case. If you turned on your Xbox manually from the power button, and then turn on the controller, the controller is synced properly to the Xbox. You can then turn the Xbox on/off from the controller too.

But, I noticed that when you turn off the Xbox directly from the power button, the next time you try to turn on the Xbox using the controller, you might encounter the sync issue. From this point, my controller will no longer pair properly. Even if I repeated turn the controller on and off, the controller will not accept any control. I will then need to power off the Xbox properly (not standby mode), turn it back on, then only I will be properly synced again.

The weird thing is, my OG Xbox One never had this issue. Must be something new to the One S/One X consoles.
