Known Issues and Bugs

• Input Validation:
  • While most invalid inputs are handled, some edge cases may cause unexpected behavior.
  • Example: Entering an empty string as input might result in an error message.
• Data Persistence:
  • The program does not save data between sessions. All items are cleared when the program exits.

Future Enhancements

• Implement persistent data storage using JSON or a database to save marketplace data.
• Add a graphical user interface (GUI) for improved usability.
• Introduce a user authentication system to track user-specific posts and purchases.
