Nowadays, promotions are being used as a medium to attract more buyers. It can be considered as one of the factors that buyers probably think before buying something. If there is a promotion, buyers are more likely to buy it rather than the one without promotion because promotions help buyers to save more money and gain more privileges.
How promotions actually help us to save more money? Easy, it helps us to pay less while we still get what we want. Therefore, we can save left money from buying for something else such as for education, for emergency, for transportation or even for food.
Consider how much money you'd spend on things over the course of a year and then that thing is on promotion discount 15% off making you can pay lesser and save more. For example, if you spend 3000 baht on personal products every year and those products are 30% off, you will save 900 baht and pay only 2100 baht instead of 3000. That 900 may be used to buy new clothes or shoes, or may be saved in a savings account. Promotions is not only help you to save more money and pay less but, it also allows you to get more products under the same budget. For example, 1 shirt costs 200 baht but during the promotion it come down to only 100 baht. Therefore, when you purchase 200 baht, you will get 2 shirts instead of 1. Or sometimes, you only have to pay 200 baht for 1 shirt and get 1 free because of promotion. If you want to have more money for doing something else, buying during promotion is the way you can save money. See promotion (โปร) that you might interested.
