Discount codes (also called promo codes, coupons or vouchers) let customers reduce the price at checkout. They're a versatile tool for marketing, customer recovery, and partner programmes.
Turning the Feature On
- Open Site Settings → eCommerce → Discount Codes.
- Toggle Enable discount codes on.
- Pick where the input appears: cart, checkout, or both.
- Decide whether codes can stack (use multiple at once) or are mutually exclusive.
- Save.
Where Codes Apply
- Cart-level discounts: reduce the subtotal.
- Item-level discounts: reduce specific products or categories.
- Shipping discounts: waive or reduce shipping costs.
- Subscription discounts: apply to recurring billing, often for the first N invoices.
Examples of When to Use Codes
- Welcome offer: WELCOME10 — 10% off first order, single-use per email.
- Cart abandonment: COMEBACK15 — 15% off, expires in 7 days, sent by automated email.
- Partner programme: Each partner has a unique code (PARTNER-X42) that tracks attribution and gives a 20% discount.
- VIP relationship: Single-use codes mailed to specific customers as a thank-you for staying.
Tip: Stackable codes are powerful but make accounting tricky. Most platforms start non-stackable and only enable stacking once you have clear rules (e.g. “percentage off” + “free shipping” combine, but two percentage discounts don't).
