Advise friends who love shopping and lottery tickets: be vigilant in front of free pies falling from the sky to avoid being cheated! ! Lottery is a means of promotion for merchants. After winning the prize, customers can choose not to receive the prize. If you think there is a problem, you can report it to the Consumers Association, the Industrial and Commercial Bureau and the Price Bureau and ask for a coordinated refund. It is difficult to determine whether it is illegal or not. Both buyers and sellers are voluntary, and there is no problem of compulsory consumption. However, false high price and discounted sales are suspected of infringing consumers' right to know. You are very happy to get the discount coupon, but in fact, the merchants are stealing! . .
