I got in early January via the online support.apple.com and booked an appointment at a local Apple Store for a replacement on my iPhone 6. Settings > Battery was already telling me this battery was toast before the proverbial hit the fan for Apple, so I lucked out as far as the price drop was concerned.
I understand this can be no longer the case (as far as finding an available battery / a speedy turnaround is concerned), but now I hear - in Canada - that thru the Apple Support App, you can actually book your battery online, and they'll let you know when one is in and have you set a time for the swap. Not sure if this is live yet, but worth noting? And yeah sorry, apparently only in Canada so far.
Via the App, users wanting to replace their battery select Get Support, select the phone in question, choose battery, power, charging as a service desired, then they are presented the option to Reserve a Battery
