Pop-up advertising itself is a very good, cheap and very effective advertising instrument1. It permits the vendor to attach the customers’ attention to their website, as well as the buyers to receive the dynamic updates on the goods they intend to purchase. When the customer will receive a pop-up alert that the TV set he likes to buy is offered at the online store he/she saw earlier with a 15% price cut, one will undoubtedly use this chance and buy it. Considering the incredibly low cost for the popups and their targeting, such a marketing tool is a much-loved thing amidst the marketing departments of big internet retailers.
