Note that the Switch is typically priced at $299.99 but given that this is a bundle that comes with two games, it is understandably more expensive. Mario Tennis Aces is already priced at $59.99 which means that you would be essentially getting two games for the price of one.
Also take note that these games are the digital versions, so for those who want the physical copy, you’d be out of luck. For those unfamiliar, 1-2 Switch is a game that was launched with the Nintendo Switch.
