Hi Rohan
Yes the Aqua Blue new 3DS are not sold by Nintendo anymore in Europe. It's too bad since lot's people like this color.
So do not have any on Stock, and I do not see them coming at all.

You can of course send me allways your 3DS, like said before the region does not matter to me.
When I send it to you, the shipping within Europe is 15€ including the insurance up to 500€ for the parcel content.
How much your shipping will be, I do not know since you have lots of options you can choose from and many Mail-Service Providers you can use.
If there is a problem with the 3DS Capture Card, I cover the shippingcosts back to you, the way to me you have to manage and pay yourself - this are European trade-rules.
One thing I do not understand, I thought your relative is coming to Germany, if this will hapen then you have to pay only the domestic shipping of 6,50€.
