1. Codes can be used on first orders only and up to a maximum pre-discount spend of £500.
2. Valid for New customers orders to the United Kingdom only.
3. Can't be used with other promo codes or on gift vouchers, delivery charges, Premier Delivery or ASOS Marketplace. Selected marked products excluded from promo.
4. Minimum-spend threshold of £20 applies to value of order when you order and when you return any items. If your returns take the revised order below the minimum-spend threshold for the code used, you'll lose the benefit of the discount i.e. items kept revert to full price and your refund will be adjusted accordingly.
5. This means you may not get the same value back when refunded.
