Old Navy offers its Old Navy Men's Slim-Fit Built-In Flex Ultimate Khaki Shorts in several colors (Flag pictured) for $15. With $7 for shipping, that's $15 off list, tied with our mention from three weeks ago, and the lowest price we could find. These shorts feature a 10" inseam and are available in regular and tall waist sizes 28 to 48, although not in all size/color combinations.
