Partrequest.com review: ripping off

When I paid $3.99 to search for a used car part I did receive several emails but only one company had the right part and all others were like advertising. The one which claimed to have right part charged $250, almost like dealer's price, while the market fair price ranges between $10 and $50 (including shipping). I did not claim refund because I knew that is the way how those guys make money. They guarentee you will receive response. Right, you will, but all trash.
