Once your order has been placed, a promotion code cannot be applied. However, we can refund the discount amount.

Please provide the promotion code you intended to use.
You can choose to receive the refund as WASO Points or a refund to your original payment method.
WASO Points are valued at £0.01 per point and can be used for future purchases.
⚠As card refunds incur a processing fee on our side, we kindly ask for your cooperation in accepting a refund in WASO Points where possible. This helps us continue providing high-quality service at the most affordable prices.
