How do I redeem my wowcher for a different deal?
Updated
Just use the box on the purchase page of the voucher that you want to buy.
If you redeem a wowcher towards the cost of another wowcher it will be of an amount equal to 100% of the purchase price of the original wowcher (inc. p&p but excluding any marketing/promotional credit) if the purchase is made not more than 30 days after the date of issue of that wowcher, or 50% of the purchase price of the original wowcher (inc. p&p but excluding any marketing/promotional credit) if the purchase is made more than 30 days after the date of issue of that wowcher but before the end of the wowcher validity period.
You can request credit here.
