7. Beware of sale items. 当心促销品。

Beware of sale items, which make you feel like you can't afford not to buy, or limited-time offers, which make you feel like you have to take advantage of a special deal. If you don't need or want something, it's not a good deal, not matter how cheap it is. A friend of mine told her husband, "I got this 50% off!" and he answered, "That means it was 50% ON."
当心促销品，因为它们会让你感到自己不能不买。也要当心限时优惠，这会让你感到占了便宜。如果你不需要或不想要某样东西，不论价格多么便宜也别买，这不是一笔好买卖。我的一位朋友告诉她的丈夫：“我五折买下的这件东西!”她的丈夫回答：“那说明原来卖贵了一倍。”
