At Target, buy one select women's dress and get a second for 50% off. Shipping starts around $5, or spend $50 or more (prior to discount) to bag free shipping. Stock and sizes may be limited. Some best bets:
Sears cuts up to 90% off a selection of women's dresses, dropping prices to $11.99. With $5.75 for shipping, that's a savings of as much as $106 and a low price for any women's dress. Some sizes are limited. A couple of best bets:
Sears offers the Destiny Women's Ruffle-Front Sleeveless Maxi Dress in Coral or Royal Blue for $11.99 plus $5.75 for shipping. That's $38 off and the lowest total price we could find. It comes in sizes S to XL, but not in all size/color combinations.
