Any sales on gold producing dragons?

[cdreams1980]

Do the gold producing dragons only go on sale for Black Friday? I know I got one of them on sale when it was first released. I've been saving up my gold, but would like to buy a 3rd nest and the diamond temple since it's on sale.

From what I can remember, they usually go on sale on release, and from time to time there have been sales as well, Black Fridays was one of them
