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 promotion method of merchants, and customers can give up receiving prizes after lottery. Those who have already purchased can report to the Consumers Association and the industry and commerce, and ask for a coordinated return and refund. It is difficult to determine whether it is illegal, and this inflated price tag deceives consumers to sell at a discount and infringes on consumers' right to know! ! . .
