中国人に諭されました。
Yes, it's not cheap, but the quality is very, very good. As a Chinese saying goes, you get what you pay for. It means that top quality goods have high prices.
Quality and price are equal, no high quality and low price of goods, can't have both.
I can't guarantee that the price I give you is the lowest, but I can guarantee that the quality of my goods is the highest, because we have always obtained long-term cooperation from customers with high-quality commodity quality and service.
