Old Navy takes 20% offmen's and women's apparel via coupon code "GROWNUP20". Although it took 20% off sitewide three weeks ago, this is still one of the better percent-off discounts we've seen from Old Navy this year. Shipping adds $7, or spend $50 or more to qualify for free shipping. Sales tax is added where applicable. Everyday Steals and jeans are excluded. Coupon expires May 8.
A best bet is these Old Navy Men's Plain-Front Dress Pants in Medium Heather Gray (pictured), Ink Blue, or Kicking Up Dust for $24 after the above coupon. With $7 for shipping, that's $11 off and the lowest total price we could find. They're available in waist sizes 29 to 42 and lengths 30 to 34.
