Gap offers its Gap Men's Classic Straight Fit Khakis in several colors (Dark Gray pictured) for $29.99. Coupon code "SUMMER" cuts that to $17.99. With $7 for shipping, that's tied with last week's mention at $42 off and the lowest price we could find. They're available in select regular and tall waist sizes from 28 to 42 with inseams from 28 to 36.
