alright I always tell people if they aren't happy with my offer keep looking and come back to me if you would like
I would suggest going here:
connectyour account and click the "Valeur de ma collection" button this way you can see what the total value is. That is where I make my offer from. Like I said I have bought something similar for $25 my final offer comes down to account value. The account itself holds no value to me.
