What did the woman buy at last?

M: Good afternoon. May I help you?
W: Yeah. I’m going camping, and I need something to keep the insects away.
M: How about these. They’re new. They’re insect guards.
W: I’ve never seen anything like them.
M: You can use them to keep insects off you-flies, mosquitoes...any insect.
W: These will keep insects off me? How?
M: They cover you. You know, like a net. You put one on your head, one on each hand, and one on each foot. You just put them over your body. The insects can’t bite you.
W: Right. Actually, I think I just want some insect spray.
M: You don’t want to try the guards?
W: No, thanks. Just a can of insect spray, please.
M: I see.
