When the customer will receive a pop-up alert that the TV set he desires to purchase is available at the online store he/she visited previously with a 15% discount, one will certainly use this chance and purchase it. Taking into consideration the extremely small cost for the popups and their targeting, such a marketing tool is a favourite thing amongst the marketing departments of big online stores.
