Problem
We currently send a single discount to the front end as the delivery discount, and we aim to display the service fee discount separately. Essentially, we want to show the original amount, crossed out, and place the word "free" next to it in a prominent highlight.
Solution #1
Add a new field in LaunchDarkly to store the discount value. For instance, if the 'serviceFee' is 300 cents, there will be a corresponding 'serviceFeeDiscount' field with a value of 300 cents, indicating the intention to deduct the entire amount.

Note that the proposed changes have synergy with the refinement to show the service fees in DMP: Feature - Show delivery fees in DMP
