Amazon's prices are already dirt cheap because of their economy of scale. You'll find it hard to compete with them for very long except where they have loss leaders. Same with eBay. eBay would be even harder because most things are way cheaper than market price or eBay exclusive. N.B. Amazon has never really made profit because Bezos keeps pouring profit back into Amazon to make prices lower and to keep customers happier.
