SellAuth has four ways to discount an order, and they solve different problems. | Feature | Triggered by | Typical use | | - | - | - | | **Coupons** | A code the buyer enters | Campaigns, partner codes, goodwill | | **Volume discounts** | Buying enough of one variant | Bulk pricing | | **Quantity deals** | Buying a set number of items | Buy 2 get 1 free | | **Bundle offers** | Having specific products in the cart | Selling a combination | ## Coupons Created under [**Coupons**](https://dash.sellauth.com/coupons). Buyers enter the code at checkout, which requires **Show Coupon Code Textbox** to be on in your [checkout settings](/guides/checkout#checkout). Your plan sets how many coupons you can have. **Code** is what buyers type. **Type** is either a percentage off or a fixed amount off, and **Discount** is the value. For fixed amounts, the currency follows the product. ### Limiting who can use it, and when | Setting | Effect | | - | - | | Start date | When the code becomes valid. Empty means immediately | | End date | When it stops working. Empty means never | | Use limit | Total redemptions allowed across all buyers | | Per-customer limit | Redemptions allowed per buyer | | Minimum order value | Order total the code requires | | Email allowlist | Comma-separated addresses that may use it. Empty allows everyone | **Count Uses** decides when a redemption is counted against those limits: * **When Order Paid** counts only completed orders * **When Checkout Starts** counts as soon as the code is applied Counting at checkout stops a strictly limited code from being claimed more times than intended while payments are still pending. Counting on payment is more forgiving, because abandoned checkouts do not consume uses. ### Scope By default a coupon applies to everything. Turn off **Apply to All Products** and pick specific products or variants instead. **Payment methods** limits the coupon to selected methods, and leaving it empty allows all of them. Restricting a code to the methods that cost you least reduces what the discount costs to run. ## Volume discounts Set per variant, inside the product. Each tier is a quantity and a percentage, so tiers of 10 units at 5% and 50 units at 10% reward larger orders. **Disable Volume Discounts when a Coupon is applied** stops the two stacking. Turn it on if your margins cannot absorb both at once. ## Quantity deals Created under [**Quantity Deals**](https://dash.sellauth.com/quantity-deals). These are buy-more-get-more offers on one product or variant. | Setting | Meaning | | - | - | | Buy quantity | How many items must be in the cart to trigger the deal | | Discounted quantity | How many of those items get the discount | | Percentage | The discount applied to those items. 100% makes them free | | Max uses per cart | How many times the deal can apply in one cart | | Priority | Higher priority deals are applied first | Buy 3, discount 1, at 100% is a classic buy two get one free. Buy 2, discount 1, at 50% is a softer version of the same idea. Start and end dates work as they do on coupons, and leaving both empty runs the deal indefinitely. ## Bundle offers Created under [**Bundle Offers**](https://dash.sellauth.com/bundle-offers). A bundle triggers when the cart contains a specific combination of products, each with a required quantity. Set the products and quantities that must be present, then a discount as either a percentage or a fixed amount off the bundle total. **Max uses per cart** and **Priority** work as they do for quantity deals. Bundles are the tool for pushing a specific combination, as opposed to discounting each product separately and leaving the combination to chance. ## How they interact Priority decides the order in which quantity deals and bundle offers are evaluated, so set it deliberately when a cart could qualify for more than one. The interaction that needs configuring is coupons against volume discounts, which stack unless you disable it on the variant. Before running a campaign, build a realistic cart on your own storefront and check that the total comes out where you expect. ## Next steps Where volume discounts are configured.
