Looks like I took too long thinking, back up to £178 now !
Just registered mine and it says that the Adobe code doesn't expire, so guess you could well buy it and sell the code on. Not sure how much you'd get for it though?
Probably only worth it if you want to use CalMAN or some other 3rd party software that the colourmunki doesn't support, right? I did look at picking up a display pro used off eBay, but they were selling used for more than you could buy them new off Amazon!
Tempted by this, I have the colormunki which I could sell, don't really need the Adobe Lightroom & CC, maybe I could sell the code too !
Forgot to mention, messaged X-Rite and they confirmed "... providing you purchase from a European Amazon account and reside within Europe then it is fine, you just need to redeem the code from us by the end of Jan 2019."
