I have some itunes credit saved over the year which was earned writing reviews / blogs. Would like to splurge it on HP but rationally it would be a boon if i could stretch my dollar at a sale. Would there be one coming soon?
Ummm…the in-game pop up stated every day that the Thanksgiving sale was the last sale for this year.
It was End of the Year sale.
So we could assume it was the last.
You can expect New Year sale 
There are sales every second month approximately.
Forget a sale; how about a GIFT for the playerbase!!!
Another DC superhero game that I play has given their playerbase in-game currency each day since last week, wishing us a Happy Holiday.
It’d be nice to received a Holiday GIFT from D3,too.
I’d be happy with a “Happy Holidays!! Here’s an Anniversary Token!”
I will be beyond Shocked if we don’t get a holiday Token, I think D3 will at least to that.
I’ll take a 3* Token 10-pack stocking stuffer, thanks.
