People are more likely to make a purchase ______.

W: I just read a curious fact. Did you know that people who spend less than ten minutes in a drugstore are five times more likely to make a purchase than those who spend half an hour there?
M: I saw that article, too. But I think, if someone runs into a drugstore for ten minutes, it’s usually to make a specific purchase.
W: And someone .who spends more time there may be just looking.
M: Exactly. Haven’t you ever gone into a store thinking that you’d buy something, and then talk yourself out of it?
W: Yes, I have. Especially when I thought I could get it for less elsewhere, or I really didn’t need it after all.
M: Exactly. But if you run in to buy something specific and have very little time, you pick it up, pay for it immediately and then leave.
W: That’s true. Maybe we should learn a lesson from that. Take your time and you’ll spend less money.
M: I doubt if that would be true in all stores, though. In a department store, for instance, you may see a sweater or something you never intended to buy and buy it because you have time to look around.
