Factual error: At the beginning, when Cindy and her friends return from shopping, Cindy's mother asks for her credit card. Cindy hands her several cards and her mother chastises her, saying that she was only supposed to take the Neiman Marcus card. Tucson has never had a Neiman Marcus.
Suggested correction: They could have gone to another town to go shopping, but there are no Neiman Marcus stores within 100 miles of Tucson.
There are two Neiman Marcus stores each about 1 hr 40 minutes from Tuscon, one in Scottsdale and one in Tempe. Plenty of time for Cindy and her friends to drive there, shop and get back. Considering both Cindy and her one friend appear to have Nieman Marcus bags, (the white bags with gold designs on them) it appears they made a road trip.
Factual error: When Cindy returns from the shopping trip with her girlfriends and hands over the credit cards to her mother, her mother chastises her for using more than just the 'Neiman Marcus' card. There is no Neiman Marcus in Tucson. The only Neiman Marcus was located in Phoenix.
Suggested correction: There are two Neiman Marcus stores in Arizona, neither in Phoenix. One is in Scottsdale, the other in Tempe, each about a 1 hour, 40 minute drive from Tuscon. Easily attainable for teenagers with a car.
