That is easy to get a higher rating  all you have to do is ship the product
fast and on time  and  90% of the time the positive feedback is posted by
the seller for the buyer.  Many ebayers never even bother checking or even
posting feedback

But I looked a lot of them have negative feedback but have a higher %  which
is normal if they sell a lot

Also many may not know they are buying a knock off or one that is not to be
sold in the US  look how many people did not know about the pet food recall
when it happened
