- Tap "+ Discount" under the item price to open the discount calculator
- Enter the discount amount as either a percentage or dollar amount and tap the appropriate button to apply it to the item
- The item price will be updated based upon the discount and a tag will be added to the right of the price to reflect this discount that has been applied to the item
- Tap "Cart" at the top of the right sidebar to return to the checkout cart
- In the cart, you should now see the discount applied only to that particular item
- Repeat this process for all items in your cart that require a discount
