The promotion looks like it ends at the end of 2017 so I suspect ad must be old.
(blush) Thank you jmontes77029, you are correct and
this is how that happened.
I usually go to UnicationUSA and seldom go to their main site:
Unication Co., Ltd.
On going to the main site today, their main page had the announcement I posted, so (sigh) I assumed "To express our thanks to all the support that you have given us, we are offering free Phase II upgrades to every unit purchased in bulk, to the end of the year (2017). Contact your local Unication office to learn more!" was real / current.
Further research now shows the original was posted 2017-11-24 and ;-) contains banners dated 20171226, so (smile) for now I'm going with "To express our thanks to all the support that you have given us, we are offering free Phase II upgrades" until somebody from Unication says different.
Apologies for the confusion!
