since it is promotion, nature also need to have a certain timeliness, so that can let the promotion can cause the attention of customers. If a shop has been doing activities, naturally there is no way to attract customer attention. So, we say that retailers use promotion but also pay attention to the timeliness, also is to clear the promotion period, the only way to give a clear time limit, can cause the customer’s attention, causing them to grab time to buy.
I visited found that many retailers use promotions seem to show no time limit, such a long time will cause customers psychological fatigue, or because of the time not clear will cause the customer misunderstanding and even disputes. Therefore, the use of retail sales as a means of promotion must have a clear timeliness.
