Two panels sit between Location and Discount on the offer form. **Stacking** decides how this offer behaves when other Lobyco offers apply to the same basket. **Limits** caps how often it can be used and how much it can give away. Store discounts are normally treated as starting prices and are always stacked. Most offers can leave these at their defaults. That means a regular offer that may stack with others in any way. ## Stacking **Where:** Campaigns → a campaign → **Orchestration** → an **Offer** block → **Stacking** **Must show:** The Allow other offers on top toggle, Stacking Priority at its default of 5, and the Apply on items selector — ideally open, so all three options are readable. **Why this shot:** Three interacting settings; seeing the defaults together is what makes them make sense. *Placeholder — replace with the image once captured. 1440px, light theme, test data only.* ### Allow other offers on top * **True** — other Lobyco offers *can* be applied over this one. * **False** — other Lobyco offers *cannot* be applied over this one. Enabled by default, on the assumption that a product isn't part of several offers at once and that offers should be cumulative — for example a 10% basket coupon that should apply across all products, discounted or not. ### Stacking Priority Sets the order in which offers are applied. Values run from 1 to 10 and default to 5, so every offer starts at medium priority and you can create higher- or lower-priority offers around it. Where two discounts share a priority, the one that expires first is applied — oldest start date, earliest end date. **Example — a "best price" offer.** To make 50% off a product the final price, with nothing applied afterwards, set **Allow other offers on top** to **False** and **Stacking Priority** to **1**. The offer is then always applied first, and no other offer reduces the price further. ### Apply on items * **Apply on all items** — applies whether or not a discount is already applied. * **Apply only on discounted items** — applies only to items that are already discounted. * **Apply only on non-discounted items** — applies only to items that are not already discounted. ## Limits **Where:** Campaigns → a campaign → **Orchestration** → an **Offer** block with a **percentage** discount and a **redemption limit above 1** → **Limits** **Must show:** Redemption limit, Discount amount limit, and the Per redemption / Across all redemptions (total) choice. **Why this shot:** That choice only appears in this exact configuration, which is precisely why the text alone leaves people hunting for it. *Placeholder — replace with the image once captured. 1440px, light theme, test data only.* ### Redemption limit The total number of transactions the coupon can be used on. Changing the redemption limit on an offer that is already active does **not** affect coupons that have already been activated or redeemed. ### Discount amount limit The maximum amount given as a discount by one coupon per redemption. Use 0, or leave it empty, for unlimited. For Product and Basket discounts with a percentage off, where the redemption limit is more than 1, you can set this limit either way: * **Per redemption** — max discount per transaction, applying to each redemption. * **Across all redemptions (total)** — shared across every redemption. Once reached, later redemptions grant no discount. **Across all redemptions (total)** applies per *coupon*, not per *offer*. If a customer receives several coupons from the same offer, the limit applies to each coupon separately. ### Maximum quantity per receipt This one sits in the **Discount** panel rather than Limits, because it depends on the discount type. It caps the quantity that can receive the offer in a single transaction. Overall, the offer discounts at most *Redemption limit* × *Maximum quantity per receipt*. **Discount amount limit** can cut in first if the amount cap is reached before the quantity one.
