The answer to that is easy…they get their money in the inflated shipping.  I had one Ebay vendor explain this to me.  Their fees are based on the selling price, so the fees they pay based on a penny are v…e…r…y small, but they profit in the shipping charge.

I ordered the car charger and it’s $3.78 shipped.  I still don’t see how a profit can be made.
