Yeah, it's very intermittent. It'll be available for 30-60 minutes for shipping at random times. I kept waffling on whether or not I wanted it and it'd go back to local pickup while I decided.
I was able to order Scott Pilgrim for shipping a few days ago. It arrived yesterday. It appears to be available for shipping again right now but it's been intermittently available for the past few days.
Yeah, it's all just stuff to make the game easier basically except for the Qawasha DLC that looks like it adds another character. I don't have that one.
It's definitely commendable although I'm at 8 months waiting for a replacement from them. Hopefully they can get Skullgirls quicker than that for people.
