I know but due to it being a collectable since it was limited in quantity, it's not that unheard of. I'm a toy collector so I know how quickly a price can jump for things.

Here it is on Amazon for way over what it needs to be.

Here's an example of what I mean by prices going up quickly. This is the power Ranger ultrazord for the season that ended in 2016. Original msrp was $30-$35. It's only barely a year old and wasn't in limited quantities at the time.

I've even seen it on some shelves still for msrp. When it comes to collecting, these things happen. If something isn't being sold by the original seller anymore, the market goes up drastically.
