Why do I always get slaughtered when I buy things?

This is the market economy. Unlike in the past, under the planned economy, prices were uniformly set by the price bureau, and there was no need to worry about being "slaughtered". Now you can shop around and shop according to the "cost performance". You already think that "being slaughtered" means that you already know the goods, and you will gradually learn to purchase. If you don't know "being slaughtered", it means that you don't even know the price, which is even worse. In fact, there are not a few people who are still counting money for others. "Smart buying can't trick bad sales." If you buy again, the merchant will not do business at a loss.
