超市打折促销的食品往往最吸引人。然而,不少消费者在购买时只关注其优惠的价格而忽略了保质期,购买时虽仍在保质期内,但难以久存。李先生就有过这样的经历:“过年的时候很多超市卖场都在促销,所以就购置了很多年货,如许多食品一下子吃不完就放在一边,等到年后想再吃的时候发现有些食品已经过期,但是丢了还是蛮可惜的。如果超市能给快过期的食品做明显标识,让消费 Supermarket discount foods are often the most attractive. However, many consumers only pay attention to their preferential prices at the time of purchase and ignore the warranty period. Although they are still in the warranty period, they cannot survive for a long time. Mr. Li has had such experience: ”When the New Year, many supermarket stores are in sales promotion, so they purchased a lot of new products, such as many foods suddenly eat aside, wait until after years of want to eat again Some foods have expired, but it is still a pity if they are lost. If the supermarket can clearly identify the food that has expired, let it be consumed.
