Altemate Courses: Alt-Step 3: The member enters search criteria to retrieve a specific item or to display a reduced list of items to browse and order from. Alt-Step 5: If changes are required, the member updates the appropriate shipping, billing, or e-mail addresses and tells the system to store them accordingly. The system will validate the changes and, if successful, will store the new information to file. Alt-Step 7: If the order requires changes, the member can delete any item no longer wanted or change the order quantity. Once the member has completed the order changes, the system reprocesses the order (go to step 6). If the member requests to do additional shopping, go to step 3. If the member needs to change the demographic information, go to step 5. Alt-Step 8: If the member's account is not in good standing, display to the member the account status, the reason the order is being held, and what actions are necessary to resolve the problem. In addition, an e-mail is sent to the member with the same information. The system prompts the member to hold the order for later processing or cancel the order. If the member wishes to hold the order, the system records the order information and places it in hold status and then displays the SoundStage main page. If the member chooses to cancel the order, the system clears the inputted information and then displays the SoundStage main page. Terminate the use case. Alt-Step 10: If the member selects the option to pay by credit card, the system prompts the member to enter the credit card information (number and expiration date) and reminds the member that the billing address on file must match the billing address of the credit card provided. The member enters the required information and requests that the system continue. The system validates the credit card account provided. If the account cannot be validated, the system notifies the member and requests an alternative means of payment. If the member cannot provide an alternative means at this time, he or she can choose either to hold or to cancel the order. If the member wishes to hold the order, the system records the order information and places it in hold status and then displays the SoundStage main page. If the member chooses to cancel the order, the system clears the inputted information and then displays the SoundStage main page. Terminate the use case. Alt-Step 11: If the order requires changes, the member can delete any item no longer wanted or change the order quantity. Once the member has completed the order changes, the system reprocesses the order (go to step 6). If the member requests to do additional shopping, go to step 3. If the member needs to change the demographic information, go to step 5. Alt-Step 12: If all items ordered are on back order, the order is not released to the distribution center.
