What promotional activities are there for cosmetics in the supermarket? Buy three and get one free.

"Buy three and get one free" is a commercial promotion activity, which means you can get one more if you buy three cosmetics. This kind of activity can motivate consumers to buy more goods and increase sales. When calculating the total price of three kinds of cosmetics, it is usually 75% of the original price, because the prices of three kinds of cosmetics are the same as those of four kinds of cosmetics. So this kind of promotion is also called "buy three get one free" or "buy three get one free".

When buying cosmetics, if you encounter a "buy three get one free" promotion, it means that you can buy three cosmetics only by paying the price of three cosmetics, but you can get the benefits of four cosmetics because the extra cosmetics are free. This kind of promotion can increase consumers' desire to buy, increase the number of goods they buy, and thus promote the growth of enterprise sales.

It should be noted that not all businesses have the strength to carry out the "buy three get one free" promotion activities. Merchants need to consider factors such as cost and profit. If the promotion activities are too frequent or too strong, it may lead to reduced profits or even losses. Therefore, consumers need to spend rationally when buying goods, and avoid excessive consumption or buying unnecessary goods due to promotional activities.
