When did Shelley and Mark go to the department store?

M: Excuse me, where can we find women’s wear?
Receptionist: On the second floor. You can take the escalator on your right.
M: Thank you.
Salesperson: Good morning. Can I help you?
W: No, thanks. We’re just looking.
M: How about this red dress, Shelley? It’s very fashionable.
W: I don’t know. I’m not crazy about red. I think it’s a bit too bright for me.
Salesperson: How about this white dress? It’s a new arrival for the season.
W: Is it? It looks pretty. But is it very expensive?
M: Let me see the price tag, It says ＄299.
W: That’s too expensive for me. I’d like something below ＄ 200.
Salesperson: What about this blue dress? It’s on sale. It’s 10% off, so it’s only ＄126.
W: Mm. I like the color. Do you think it’ll look good on me, Mark?
M: I think so. Why don’t you try it on?
Salesperson: What size do you take?
W: Medium.
Salesperson: Here’s a medium in blue. The fitting room is fight behind you.
W: What do you think of it, Mark?
M: It’s very nice. I think blue suits you. And it fits perfectly.
W: Great. I think I’ll take it.
M: That’s a good deal.
Salesperson: Will that be cash or charge?
W: Cash, please.
