DDO Store Sales & Promotions, is there a pattern? is it random?

[TacRedline]

Is there a pattern of what goes on sale that's followed throughout the year on these sales? Or is it random?

Anyone track it?

Thanks!

Store sales are tracked here, going back just over four years. The actual schedule is semi-randomized, but you can use the history to predict the next occurrence of any given sale reasonably well.

Same deal with Bonus Days.
