How the hell is anyone meant to make any money then?Things don’t retain their value for life. Your method will see items increasing in price every time they are sold. If I was to buy this, and shipping was about $150, suddenly a $350 bike is $650.
You're entitled to ask what you want. I just don’t think charging others the postage etc you pay, plus new postage fees is in the spirit of things.
