A: This is the first time I've seen these batteries on sale. B: I'm sorry, but they aren't on sale today. A: Look at the ad. The ad says they're on sale. B: Yes, the ad says that the other brand of batteries is on sale. A: Yes, I misread the ad. B: Believe me, you're not the first person to make that mistake today. A: No wonder people make a mistake. The price is in big letters, and the brand is in tiny letters. B: You're right. You have to read an ad two or three times sometimes. A: You have to be careful with every ad you read. B: It's okay. I'll go get you the batteries that are on sale.
