They get their percentage from the total sale. Item + Shipping+ Taxes = Total that take their percentage cut from. They then make more money. Why nobody wants to use it anymore. I tried once. They kept changing the shipping from what I wanted to change. Which was $7.00. To what they wanted me to charge. Which was more than double that. My cousin who use to sell a lot of things on Ebay said you have to go through this whole procedure to refund the difference to the buyer. She quit like many people I know did. Their greed might be their doom. Or it was be just stuff from China selling there.
