I remembered that when I was in college, I was short of money. So every time when I went shopping, I would try to buy some cheap ones! For example, I would
buy a pair of sneaker, which cost just 40 Yuan. And after a month, I found I was bullied and that pair of sneaker was no use any more!
It is really a pair of junk shoes! 这双鞋真次!--
junk:垃圾 junk food!垃圾食物!来源：
千万不要买junk car. That's dangerous!--
good buy 不等于 goodbye!
还可以说:That's really a bargain!
bargain 动词(讨价还价)!名词(便宜货)!
