How do I apply discounts?

Discounts work on two levels, each supporting a fixed amount or a percentage:

• Item discount: tap an item in the cart → choose "Discount" → enter an amount or percentage.
• Cart discount: tap the "Discount" button below the cart.

Each item and each cart can hold one discount at a time — applying again overwrites the previous one, and tapping the discount badge removes it. Discounts are applied before tax, the standard order in retail.
