Character slot expansion discount.
You just missed it. Character slots were on sale on Friday 1/3/14.
I never saw them on 1/3/14. I checked when I heard the rumors… they weren’t there for me.. they were still 800 Gems.

Was it 1/3/14 on the west coast of the United States? They had a specific time frame, and a countdown timer on the sale. I bought 2 slots for 500 each (I think, numbers don’t stick in my head, but definitely not 800 each).
These slots have gone on sale fairly frequently enough that if you are just patient they’ll drop.
