Input:  Person1:     Good morning , Jason . How did you sleep ?  
 Person2:  Pretty well , thanks . Still feeling the effects of jet lag a bit , but last night I got at lease six hours of rest .  
 Person1:      Great ! So , are you ready for a full day of shopping ?  
 Person2:  Yep . Let's do it . I'm pretty excited !  
 Person1:      I know a place that should be perfect . It's called the China Friendship Shopping Center and it's pretty much like an American mall - except with more variety . You can even buy a live chicken there if you want .  
 Person2:  Live chicken ? Thanks , but no thanks . So ... tell me about bargaining . How can I do it like a local ?  
 Person1:      Well . I'll be honest and say you'll never be as good at bargaining as a local person . You're a foreigner and the sellers can see that . But ... if you're smart , you can get bargains that are not too far away from the local price .  
 Person2:  Cool ! Teach me !  
 Person1:      For starters , you want to do a lot of scouting first . You've got to know what things cost .  
 Person2:  Someone told me to go to a convenience store and see how much a soft drink or a tube of toothpaste costs . The idea is that by comparing the prices of those items , you can figure out the relative prices of everything else .  
 Person1:      That could be helpful . But when you go into a shopping center ... prices become very flexible . You have to be able to read the market .
