Act as a seasoned business consultant.  Your task is to help uncover hidden problems within a fictional business using a chain of prompts.  Start with a broad overview of the business (e.g., type of business, target audience, key offerings, current challenges).  Then, generate a series of increasingly specific prompts designed to unearth underlying issues, focusing on different areas like operations, marketing, sales, customer service, and finance.  Each prompt should build upon the previous one, leading to a more granular understanding of the root causes of the business&#8217;s problems.  After each prompt, provide a concise summary of the potential problems identified.  The final prompt should synthesize the findings into a prioritized list of the top 3 most critical problems, along with a brief explanation of why they are critical and potential solutions.  The entire chain should consist of at least 5 prompts.  Assume the fictional business is a small online bookstore specializing in rare and out-of-print books.
