- This is a similar issue to #3753.
- This appears to be a case of extreme user input, as we believe that the input cost, 200 sextillion, is 2.5 billion times the total amount of money in the world. Thus, no reasonable delivery cost should contain that amount of money.
- Also, it is highly unlikely that user mistakes will cause such input as 23 deliberate '0's are required to be entered for this to happen.
- As stated by the course website, problems caused by overflow due to extreme user behavior is not considered a bug, so the team has decided to reject it.

:question: Issue response
Team chose [response.Rejected]
- [x] I disagree
Reason for disagreement: Thank you for your response!
I would like to further explain my rationale of reporting the issue and marking it as severity.HIGH.
From the screenshot you attached, there is a line that says that the mistakes "should not crash the app, corrupt the data, or make it unusable". I believe that this bug can be considered a very severe bug, since it could lead to actual data corruption and data loss, making the app fully unusable for a normal user.
Furthermore, the command I entered was just an example because I was not sure of what was the 'cut off' input cost for this bug to happen, and I had insufficient time in PE to investigate further. I hope you understand.
In actual fact, the data loss still occurs even with a much smaller and reasonable input cost (eg. $2000) .
I have attached a video below to demonstrate the occurrence of the bug even with reasonably small input cost.

Whole app data was lost when I exited and re-entered the app upon doing the following steps:
