Backcountry takes 50% off outlet items via coupon code "50BUMP". (Note that the 50% is taken off the full price, not the outlet price.) Shipping starts at $5.95, or spend over $50 to qualify for free shipping. Some exclusions apply. A couple of best bets, with prices after coupon:
Last Call by Neiman Marcus offers the Casual Couture Women's Faux-Leather/Jersey Combo Dress in Black for $24.12 plus $5 for shipping. That's tied with last week's mention, $134 off, and the lowest total price we could find. It's available in sizes XS to L. Deal ends October 1 at 9 am ET.
