                  This time when you run it, this happens...













                             What’s going on here?








                  The program is no longer displaying a price. So what happened?



                  The price moved
                  The web page for loyalty customers is much more dynamic that the old
                  web page. The page for regular customers always displays the price in a
                  substring beginning at index 234. That’s not true for the loyalty program
                  web page. The price on that page can be almost anywhere. All you know
                  for sure is that the price follows the substring >$:

                                                                     in the string.







                                               All you know is that the price
                                               follows these two characters.


                  You need to search for the price string.
