Amazon Discrimination II Planet of the Apes isn't the only DVD that has different prices at different times. Recently, on-line shoppers logged onto the DVD Talk Forum, a chat room dedicated to discussions about DVDs. These shoppers noted that Amazon's price for a limited-edition copy of the Men in Black DVD could differ, depending on a number of factors. Among the determining factors, they said, were the following: which browser was being used, whether a consumer was a repeat or first-time customer, and which Internet service provider address a customer was using. Were prices higher or lower for repeat buyers? Explain your answer.
