👉 Since your resolvedItems is already storing price, quantity, and total, you could skip discountPrice unless:

1. You want to show original vs discounted price separately, or

2. You expect item-level discounts in future.

⚡ My recommendation:

• If you only apply discounts on full order (like voucher/coupon): ❌ remove it.

• If you plan per-product promotions (e.g., “Shirt 20% off”): ✅ keep it.
