I'd like to buy a bottle of Centrum , a dozen tooth brushes , some baby's wipes , and a small bottle of aspirin .   Centrum ? We have bottles of thirty and one hundred tablets . Which kind do you want ?   Give me one bottle of one hundred tablets .   And what kind of toothbrushes would you like ?   Can I have a look at them ?   Sure . This brand is supposed to be very good , but they're expensive . Those are new products . They come in several colors and sizes . There is also hard , soft , and medium .   Are they cheaper ?   This one is 10 % off . That one has no reduction , but you can get a free tube of toothpaste with six toothbrushes .   So if I buy a dozen , I'll get two free tubes of toothpaste ?   That's right .   Good . I ' ll take a dozen of them then .   And here is your aspirin . What else did you say you want ?   Baby's wipes . Johnson's .   Anything else ?   Well , actually I'd like to buy some vitamins for my son . He's five months old . Can you suggest any ?   Sure . Here you are . This one is excellent . Just mix one drop of it with milk .   Thanks . That'll be all .
