During the promotion (โปร), there are many privileges and other benefits that will impress you as a customer. Sale or discount is one of the most popular and widely used for attracting more buyers as it allows customers to pay less and save more, making it becomes one of the factors in making decision when purchase a product. Customers will no longer have to pay at full price and they are able to save more money because they have money left in their pocket more than ever after shopping. To illustrate this, imagine if you used to pay for clothes 10000 baht a year, since you purchase only when it’s on sale (ลดราคา) and promotion rather than with out one, you pay less from 10000 baht to just 5000 baht, leading to more saving. You can use the other 5000 baht for education, food, other monthly bills, or even travel. Therefore, buying things during promotion or sale is more preferable and shouldn’t be overlooked.
