An efficient budget covers the cost of the customer demand that your voucher generates, for the duration that you set. For example, if a product is selling an average of 20 units per day without a voucher, and you want to run a £5 off voucher for 10 days for this product, the minimum budget you set should be: (number of days x number of average daily units) x (discount amount + redemption fee). In this example (10 x 20) x (5.45). £1,090 should be your minimum budget.
Avoid creating low budgets (less than £100) for deep discount vouchers, such as 80% off or £35 off. Low budgets for high discounts will cause your budget to expire rapidly in a couple of hours. As a result, only a handful of customers will be able to see and interact with your voucher.
If 80% of your voucher budget is redeemed before the voucher's expiry date, we remove the voucher from the website, so that it is no longer visible to customers. Customers who collected the voucher before its removal from the website will still be able to redeem the voucher until the expiry date.
