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. Deal ends May 24.
