When web companies make a mistake like forgetting to renew a domain it can often be very costly. The AP reports that domain grabbers capitalized on the mistake of a web company that worked for the George W. Bush Presidential Library. The Bush Library web firm forgot to renew the www.GeorgeWBushLibrary.com domain and a domain grabber scooped up the domain for just $10 when it lapsed. The George W. Bush Presidential Library then had to buy the domain back for $35,000.
