A、T-shirts on sale always have a poor quality. B、People shouldn’t always believe in the advertisement. C、People should not buy d

M: I’m never going to shop at Sun Fashion Shop again!
W: It’s not one of my favourite stores either. What happened to you there?
M:[9]They were advertising a "Clearance Sale" in front of the shop and I bought two T-shirts for $30. [10]The problem is that the shirts shrank to children’s size after being washed only once!
W:Did the shirts have laundry instructions on them?
M: Yes, and I followed them exactly.
W: Did you try to get your money back from the store?
M: Yes, but they said they don’t guarantee their products. I’ll never shop there again!
W: That’s why it’s not my favorite store, either. There are other, better quality stores that will refund your money if there is a problem with one of their products. It’s just not worth taking a chance when stores use so-called "price cutting" techniques to mislead shoppers into buying poor quality products.
M: Yeah,[11]they are misleading with their beautiful advertising lies!
W: If enough people become aware of their poor quality and their lies in advertising, the store will not be able to stay in business because no one will shop there.
M: I hope you’re right. Stores like that should not be in business.
