You had better not go into a supermarket when you are hungry, or you’ll probably buy more than you plan to. You need to know how to buy things at the supermarket. You should consider if you really need these things. You shouldn’t buy anything just because it’s cheaper than usual. Sometimes, you still need to read the list of ingredients(原料) on the back when you are choosing some food.
Compared with famous brands, you should choose ordinary brands. Ordinary brands are in plain packages. These products are cheaper because producers don’t spend much money on packing or advertising. However, the quality is usually as good as the quality of famous brands. When you are buying clothes, you can often find brands of high quality and low prices that are not famous.
When you want to buy some clothes, you can shop in discount clothing stores. It can help you save a lot of money. Although these stores aren’t very attractive, and they usually do not have individual dressing rooms, clothes are low in price there, and you can often find the same famous brands that you find in high-priced department stores.
