The following:
Since I moved out and my little brother often plays with the Nintendo Switch, he asked if he could buy it from me. Of course I said yes. Back then I paid (more or less spontaneously.) 350 euro. Do you think it's "anti-social" if I ask him to pay 350 euro? Since I got the switch, he has mostly played on it.
About that I spontaneously paid 350 euro:
My ex had to pay a fine of 800 euro and asked if I could pay half because he actually had to pay it because of me (he drove more tons than he was allowed to drive). I could just pay 350 euro. After the end I said that he can give me the switch instead of the money, because he will never play with it anyway.
You are asking for the new value for a used product and not the current value
Mega social! So first of all the console is already used, for that reason alone I would easily pull a hundred and it's your brother! You make good prices because you don't want to take your last siblings off their last shirt! So personally I would ask a maximum of 150 euro.
I would not sell anything to my siblings…
I find it anti-social if you want to benefit from the family.
Most objects lose value over time. Not even a stranger would pay the 350 euro for it. And then within the family, that's definitely associative.
You don't have to give it to him, but I would find more than 150 within the family very strange.
So I think you can sell, but just at a reasonable price, because you don't just give away a switch, it's too valuable for siblings.
Why Benefit? If I give it to him for 200 euro or so, I won't benefit? Especially if only he actually played with it.
To ask for the new price for a used device and then within the family is already thirty. You don't have to give it to him, but that is assi
