twitter and e-mail. heather s. asked, i recently got a speeding ticket. how do i know what i owe? >> how much money do you have? send it. you have no idea how expensive it is. the price if you go to

america. they set up this rating schedule. all of the movie makers pay into it, and then they put a -- you know, a g on it or the r or whatever rating, then they send it off to the theaters. then the theaters can do whatever they want. there are no rules about this. there are no punishment for the theaters. the theory was they take so much heat from the local population that they would stick with the rules. the majority of them do. so if you don't like it, complain. >> good idea. a guideline, not a rule or a law. nancy s. e-mailed, if an item is purchased and then shortly thereafter reduced in
