Frequently asked questions
Where should the minimum spend sit?
Above the current average order value, close enough that reaching it means adding one item rather than two. Too far above and nobody uses the coupon.
How much should a coupon be worth?
Less than the contribution on the basket uplift it produces. If reaching the threshold adds £18 of contribution, a coupon worth more than that loses money on every redemption.
Should coupons expire?
Yes, urgency drives redemption and an open-ended coupon becomes a permanent price cut. Two to four weeks is a common window.
Do coupons attract the wrong customers?
Public codes do, because they reach people who would never have paid full price and who churn quickly. Targeted codes to specific segments perform far better.
