Nothing at all wrong with flipping. After all isn't this what all middle men and end of the chain retailers do in every business in the world. They buy at a low price and ( hopefully) sell at a higher price.
for someone to say they think its wrong shows ignorance of how commerce works in the world , or maybe they think we should all get OEM driver heads for the $20 it costs to be made
not to mention the principles of supply and demand which is the case with these balls.
Bottom line, don't want to pay a certain price for an item , then don't, but don't cry because somebody else is willing to pay that price and somebody is making a profit.
