Many people in Beijing Book Building have discount cards because they have certain benefits. These scalpers get discount cards from some channels at low prices, and then sell them to consumers at a price of about 9.5 fold in the book building to earn the difference. On the surface, consumers get preferential treatment, but in fact, they may not enjoy complete after-sales service because they bought the discount card of scalpers, such as not being able to return goods.

In addition, the behavior of these scalpers chasing customers to resell shopping cards has also seriously affected the normal public order in this area. Therefore, we appeal to consumers not to buy discount cards from scalpers, and suggest that relevant departments strengthen supervision, crack down on such illegal acts and safeguard market order and consumers' rights and interests.
