The post did not not say buy five and get one free it said:
"Something like purchase five new LE's in a year and receive a
-special edition Christmas ornament-
only for those who purchased the five or something like that.
The one free would not be a LE but a small piece like an ornament that would be only for those who purchased the five LE's. It would not be available for retail sale, thus also making it very collectible.
