When Premium Stash Tabs will be back on sale?

I know I've seen the premium stash tabs bundle on special several times, but wasnt sure if it was on any kind of regular schedule, does anyone know?

I wanted to buy a few more bundles, but hate the idea of doing it and they go on sale again the next week

I would guess that it will be this weekend or next.

Premium stash tabs is probably the MTX that is on sale most often, so don't worry, just check daily.

They are often on sale over weekends, and it happens at least once every month, sometimes twice.

thanks for the info
