Today through june 6

Thanks, think they will add the feature to the store later in the day?

Yeah. I was under the impression you just bought a rune page and you got 2 on your Rune page - This is clearly not the case. Also there is no "item" at this time in store marking 2 for 1. Hopefully it'll release soon.
