Selling arms to Saudis: count this as democracy promotion

"Saudi Arabia has asked the United States for prices for surface warships with integrated air and missile defenses, helicopters, patrol craft and shore infrastructure, the U.S. Navy said on Friday.   The Navy is preparing a rough cost estimate that would be delivered possibly as soon as May, Navy spokeswoman Captain Cate Mueller told Reuters."  Do you know how much the US overcharge Saudis for things, especially arms? I am sure that there is a special pricing table reserved for Israel.
