If you have applied your FANATICAL15 voucher code to your order, but the discounted amount remains at zero then the cause is that the products in your basket are excluded from the voucher.
We denote these products with ' the best price is already applied '.
I am sorry but if nothing is deducted then you will not be able to use this voucher code on this order. The best price for the products have already been applied on your order.
