一．一件小事体现一条“生意经”的犀利某自认为是聪明的消费者,被交际圈内的所有人称为“理性分析的巾帼英雄”的女士,叙说了自己的一次消费经历:有一回逛街,遇上一个平价品牌在打折,便认真挑了两件上衣排队去付款。收款小姐说:“两件8折,三件5折。”我一时没回过意来,但凭直觉反问收款小姐:“有差别吗?”收款小姐嫣然一笑,没有回答。我却傻傻地站在那里,花了一分多钟的时间才在心里把账面盘算清楚:“对呀,只有傻瓜才会买两件而不是买三件,因为买三件不仅比两件多了一件,买三件的钱比买两件的钱还要少。”“付更少的钱还平白多了一件衣服,何乐而不为?”我拎着三件衣服走出收款专柜,乖乖地服膺了收款员小姐告诉的商品促销逻辑。本来可以什么都不买的,可打折却让人见奇心喜;本来可以只买一件的,但算算看看,一件九折,两件八折,早晚用得着,何不就买上两件?本来两件就足够了,但买三件比买两件还便宜,为何不再挑一件呢? one. A trivial matter embodies a sharp consumer who believes to be a smart consumer and is called “a heroine of rational analysis” by everyone in the circle of communication. She describes her own experience of spending one time: shopping. The last cheap brand was at a discount, and then carefully selected two shirts to line up to pay. The collecting lady said: “Two 20% off, 30% off.” I didn’t get back in time, but instinctively asked the receiving lady: “Is there a difference?” Miss Ms. smiled and did not answer. I stood there innocently and spent more than a minute of time thinking about it in my heart. “Yes, only fools will buy two things instead of three, because buying three things is not only two things. There is one more thing. Buying three pieces of money is less than buying two pieces of money.” “Fewer money and more white clothes, why not?” I walked out of three clothes. The counters slammed the merchandise promotion logic that the cashier said. I could have bought nothing at all, but I was surprised to see discounts. I could have bought only one thing, but if I had to take a look, I would have to pay 10% off, 20% off, and sooner or later, why not buy it? Two of the original two are sufficient, but buying three is cheaper than buying two. Why not pick one?
