They sell out very quickly on Apple's refurb website. You've got to look continuously throughout the day and be ready with credit card in hand. Here's an interesting fact. The 2015 15" refurb that I'm typing on right now, was purchased one month ago from Apple. When I got it, it looked brand new...and probably was. coconutBattery says it was manufactured on 9-26-2016. However, coconutBattery also says the battery was manufactured on 8-25-2015. Odd that the computer is only 99 days old and the battery is 497 days old. Regardless, both work like a champ!
