Disgaea 4 would like to say Hi. They had to discount that to sell out. I saw both limited editions go for $60 and $30 before selling out
Key word was "I" as in, I personally can't recall a time, not, they've never done it. It was meant to show it was pretty rare / borderline never happens.
And now I can say that Mugen Souls is the only one I've seen go on sale.
Isn't the MSRP $100, which it is still at?
