Even if 7 add shipping costs, Amazon is typically more expensive. I order my car parts from rock auto and have NEVER found Amazon to be cheaper even after adding shipping costs. They were cheap maybe a decade ago when they were trying to fold everybody else but they got enough fools by the short and curlies to start jacking prices up until people start looking elsewhere. Same formula as Wal Mart, it’s a proven good practice for big corps to kill local and small businesses.
