I don't bargain when shopping.

Just to tell you, the easiest way is my experience ~!

Generally speaking, the price of products sold by merchants is definitely in contrast with the cost and profit. Simply put, it is twice the cost. At this time, it is necessary for you to bargain. If I buy a product, I will cut off the profit of this product and then add about 7% appropriately to get the goods. This is psychological warfare.
