Merchants can generally participate in the lucky draw with a small ticket of more than XX yuan. The prize is a high voucher, and the probability of winning is extremely low. In fact, as long as you participate in the lucky draw, you basically get high-value vouchers.
Then the clerk will suggest that you use this high-value voucher to spend in the store, but at this time the jewelry placed in the store is basically a fake product. Basically, the price you pay is the actual value of the jewelry you buy, and even the value of the jewelry you buy will be lower.
