I remembered 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!（音乐）

1）It is really a pair of junk shoes!这双鞋真次!

junk:垃圾 junk food!垃圾食物!

千万不要买junk car.that's dangerous!（音乐）

2）That's really a good buy!真实便宜货!

good buy=/goodbye!

还可以说:That's really a bargain!

bargain 动词（讨价还价）!名词（便宜货）!
