How does HBN measure the discount percentage?

For the Maximum discount percentage rule, the app uses:

1. Original price = the item's Compare-at price if one is set; otherwise the pre-discount unit price.
2. Final unit price = the unit price after all discounts are applied (codes, automatic discounts, other apps).
3. Discount % = (original price − final unit price) ÷ original price × 100.

Details:

• If a Compare-at price exists, it becomes the starting point, so the calculation matches the markdown your shoppers see.
• If no Compare-at price exists, the pre-discount price is used.
• The calculation is per unit, so a cart with quantity 3 is measured correctly.
• Stacked discounts are added together; the app does not count them twice.

Example: Compare-at $100, final unit price $70 → discount is (100 − 70) ÷ 100 = 30%. A rule capped at 25% would block checkout.
