Nintendo 3DS + games selling price?

I have a nintendo 3DS (no great signs of wear) with the games Pokemon Ultramond, Pokemon alpha sapphire, pokemon mystery dungeon team blue and New super mario bros 2. I asked gamestop how much I got for that and I thought so: get almost 100 euro. My question is now how much do I get? Almost 100 euro is not enough, because I bought the Nintendo for 100 euro, ultramond for 36 euro, alpha sapphire for 36 euro, mystery dungeon for 20 euro and new super mario bros 2 for 30 euro. So how much do I get about on ebay (classifieds) for it?

80 euro if it is the "NEW" version.

Depending on where you sell it.

Is the normal 3ds. And I meant with the games together how much I get about

The 3DS has been on the market for a while now and of course your copy is not brand new. Just like the games.
100 euro is a very fair price and I'm actually less used to gamestop.

Alternatively, you could be smart about how much things go away on Ebay and adapt to it.
But you should not expect too much.

At the most 10 euro per game and the console 50 euro or 60 euro

Look at what has been paid on Ebay. (Closed Quotes.) This applies to your console and then the games. Summarize and you have a good value.

Ev. But you are better off if you do not sell everything together in a pact.

3DS and one or two games. And, depending on the value, sell the other games individually.

Do not forget pictures & descriptions in your offer.
