通常 W (30~33.) People want to give gifts on special holidays. How much do they usually spend on gifts? A study shows people spent about $1,000 on gifts in 2020. This is about 10% more than that in 2018 and 20% more than that in 2016. Here are ways to help you shop smartly. First, there is no need to buy gifts for everybody. You can show your love and care by writing a card. Next, shop with a plan. It is great for you to make a list before going shopping. 傅培 Third, if you don't need a lot, don't buy sets Clerks may talk you 寶石 into buying more by showing you sets because they look like a great value. If you don't think carefully, you probably spend more money on useless things. Fourth, don't buy more to save more. Clerks might ask you to buy three because you can get one for free. In fact, smart shoppers never shop more than they need. So, think twice before you buy something. value useless (C) 30 Which is right about the cost of gifts on holidays?
