Deal-of-the-day

Deal-of-the-day (also called daily deal or flash sales or one deal a day) is an ecommerce business model in which a website offers a single product for sale for a period of 24 to 36 hours. Potential customers register as members of the deal-a-day websites and receive online offers and invitations by email or social networks. As of 2011, deal-of-the-day sites have continued to grow in popularity, although new concerns have arisen over the longevity of the concept and the financial viability of one-day deals for small businesses.
