This is not a game that is going to go on sale, and you are highly unlikely to see anyone selling it for less than $60 second hand. And after March 2021, the prices will only go up from resellers. So either way, if you wanted the game regardless of the pins, you would have had to pay full retail price at minimum. The cheapest you'll find it is at Walmart for $50 like they do with most of their games. The only thing that happened here is that you bought it maybe a little earlier than you wanted for a chance at the pins.
I like everyone else it seems don't care so much about the pins as the time spent trying to get them when Nintendo knew that very few would get them. It's just bad to offer something like this and not having nearly enough for everyone who got the game to be able to get the pins. They should have just sold the pins at $29.99 a set if they were going to be so limited, or possibly much higher if what I hear about ebay prices is true. Better yet just sell a limited edition of the game at a higher price with the pins. Nintendo wants that site traffic though apparently but I don't see wasting anymore of my time on there anytime soon as least.
