A buying, accumulating, and drawing method is provided to draw a winner through automatic drawing using a program if target accumulation is completed in a shopping mall and an open market by purchase of customers, and draw the winner again by rotating the target accumulation. If the customer buys a specific product, the number of purchases is automatically accumulated. If the number of accumulated purchases is reached to a specific number, the drawing is automatically performed by the program and the winner is drawn. Winning is informed to the winner through an SMS(Short Message Service), an email, and other communication tools. The winner is repeatedly drawn again by rotating the products after the drawing. |
