[EXPIRED] Rocket League Ultimate Edition – Xbox One is Just $18.00 at Amazon

In what seems to be an odd pattern of price fluctuation, Rocket League for Xbox One is back down to just $18.00 on Amazon. It’ll likely jump back up to $30 any moment now. For what it’s worth – Rocket League is my absolute favorite game right now. I’ve logged an embarrassingly high number of hours playing it, and I think you should all join me.
