How expensive will Super Mario 3D Allstars be in early 2022?

I want to buy Mario 3D Allstars for the Switch, but since I don't have any money for it at the moment, I can't buy it until the beginning of 2022. But now the thing is that Nintendo will no longer sell the game from March 31, 2021. That means I could only buy the game retail on Ebay. Of course, the game is then also more expensive. Can someone who is familiar with it estimate how expensive the game will be in early 2022? How much surcharge do I have to expect?

The price won't go up that much until 2022. Nintendo has made a very large number of copies available by the end of March, so 3D All Stars will not be uncommon! It might cost 70 euro. Probably less. (Please note that this is my assessment. I could be wrong too!)

From then on they stop production, but there will still be games in the trade, including second-hand stores.

Because of this announcement, many have also bought several copies, so that there will still be enough on the used market.
