Why are you reading the classifieds ? What do you need ?   I'm looking for a bookcase , but I don't want to buy a new one .   Are you having any luck ?   Not really . There aren't any used bookcases listed . But there are a few rummage sales on Saturday . I think I'll go to them .   Do you mind if I go with you ?   Not at all . These private sales are great places to bargain . And sometimes you can find terrific things among all the junk .   I learned to negotiate from my mother . I thought I was pretty good at bargaining , but I had a problem the other day at Kimble's Department Store .   What happened ?   I wanted to buy a beautiful wool sweater for my girlfriend . It was priced at forty dollars , so I started by offering the salesclerk thirty .
