TASK
Your final task is to generate an “Iceland Receipt” given an order id (to be submitted from a form textbox).The receipt should show the delivery, payment and order details. In the order detail section, all items should be listed and
grouped according to their categories. The order of items does not matter. The receipt should show the grand total and
discount/refund (if there is any).
- Discount – customer paid less than s/he should.
- Refund – customer paid more than s/he should.
