Discounts and coupons now count their usage correctly, so use limits are applied exactly as you set them up.
- A coupon limited to one use per customer is applied to just one eligible item in the basket and leaves already completed orders alone.
- A coupon counts as used as soon as the purchase is paid, so it cannot be used a second time.
- Shop purchases now count towards a discount's usage, which previously was not recorded at all.
- When a purchase is refunded or removed, the discount's usage count and customer list are reduced again straight away.
- Usage counts that had already drifted have been recalculated from your existing orders and pass purchases, so what you see now matches reality.
