Target discounts a selection of women's dresses to $25. Even better, add two to your cart and apply coupon code "TGTWDHM6" to cut the price to $45. Plus, all orders receive free shipping. That's $22.50 per dress and savings of at least $35. Deal ends January 9. A couple best bets, with prices after coupon: Orders placed by December 20 are guaranteed to arrive in time for Christmas.
