You could offer a 24 hour only special deal. Offer a new one daily.

Hi KW, We hope that you are enjoying the best that life has to offer! Thank you for your suggestion! We have received similar feedback from customers who also enjoy the thrill of the hunt for the occasional steep discount! In fact, it is actually through feedback from customers that we have decided to offer 2 separate web sites: Zappos.com and 6pm.com. Here is an explanation of the difference between the 2 sites: Zappos.com is for customers who want the very best customer service and the very best selection, with free shipping both ways, a 365-day return policy, and 24/7 customer service that is above and beyond what you would normally find at any retailer anywhere. 6pm.com is for customers who are looking for a large selection of products at deep discounts. It does not offer free shipping both ways and the return policy states that you can only return items within 30 days. Reducing our costs enables 6pm.com to offer really deep discounts; as much as 75% off! Look for even deeper discounts in the future as we continue to add more selection to 6pm.com. We decided that we would prefer to be known as a service company since it is more consistent with our goal of focusing mainly on customer service rather than on having very deeply discounted prices. If you have any additional comments or feedback, please do not hesitate to let us know. Have a wonderful day! Thank you, Zappos.com

It is a good idea to keep the special offer site separate as this allows the flow of the main site to remain
