The Nintendo Classic Mini is a kind of End-to-End closed gaming console which lets us play the old classics from the original Nintendo NES. It has a fixed amount of only 30 Games playable on its flash meomory and comes with one Controller. It was announced in mid of this year for the release on 11.10.2016.
Currently eBay.de prices and sold listings are more than 200% above retail price (70EUR). Therefore this makes this console a very good investment even before official market release.
I found out about this investment just beginning of this week and every available source seemed to be sold out since a few month, but there are/were still places where to find it online, see possible sources below:
I was able to buy 3 pieces of it this week and they will make a fine profit. If you cannot find any consoles left in the online stores I would suggest to check-out the next electronic stores before everything is sold out.
Rumors are there is only a very limited first batch from Nintendo and only in 2017 there will probably be a next production batch.
Good luck in finding any consoles left!
