Gap Factory takes 15% off sitewide, including clearance items, via coupon code "NOSC15". Shipping adds $7, but orders of $100 or more (before coupon) qualify for free shipping. Some exclusions apply, and available sizes and quantities for many clearance items are limited. A couple of best bets, each with prices after coupon and $7 for shipping:
ModCloth offers its ModCloth Women's Home Movie Star Hoodie in Navy for $24.99. Coupon code "STYLE4U" cuts it to $21.24. With $5.99 for shipping, that's $29 off list and the lowest total price we could find. It's available in sizes XS to M.
Prefer another color? It's also available in Berry for $22.94 via the above coupon.
Woolrich offers its Woolrich Women's First Forks Hoodie in Cardoon, Carmine, or Deep Indigo for $39.99 with free shipping. That's $25 off and the lowest total price we could find. It's available in sizes XS to L, although not in all size/color combinations.
