The online store 6PM has a sale running for today.Log In It is for 65% off already marked down clearance items for Martin Luther King Day. I shop this store often for myself and my teens and Love their sales.
I love the deals that 6pm offers but beware of their return/exchange policy. They DO NOT offer exchanges and returns must occur within 30 days. 6pm is owned by Zappos I believe, which is a pretty major retailer, so you'd expect their return policy to be a little more lenient. I think this is due to the fact that they offer many out of season products and discontinued lines (also why they can offer such amazing discounts). Just clicked OP's link and found a $268 dress for $30, not bad!
6pm is a great website. I recently purchased a pair of Reebok running shoes for only twenty three dollars and with free shipping. It was a fifty four percent savings. I was so surprised when I saw it so I bought it immediately.
