I want to buy some flowers for my wife's birthday .   Red roses are always a popular gift for birthdays .   What are the roses going for ?   They're only $ 20 a dozen .   That sounds nice and cheap .   Yes , you're saving money because they're on sale today .   Okay , give me the roses .   Could I interest you in anything else ?   No , but thanks anyway .   Your wife will be thrilled with the roses .
