Having issues with your discount code?

Your code: Have you entered the code correctly? Our codes are case sensitive, try copying and pasting the code into the Discount Code box just before checkout.

Expiry Date: Please look at the terms and conditions of the discount code to make sure this offer is still valid.

Eligible items: From time to time we offer discount codes for selected items only and this will be stated in the terms and conditions of the discount code. 

Unique Codes: If you are lucky enough to receive a unique code from us, please note that it cannot be used in conjunction with any other discount code and the code can only be used once.

Why has my order been cancelled?

If your order is cancelled, we will send you an email within 48 hours to confirm the cancellation of your order and reason(s) why.

Do I need to be in to sign for my delivery?

Due to the size of our parcels, it may be necessary for somebody to be present in order for the products to be delivered.

We therefore recommend that you select an address for delivery where there will always be somebody present to accept delivery and (where required) sign for the delivery.

If no one is available at your stated delivery address to take and (where required) sign for delivery, we will leave you a note that the products have been returned to our premises, in which case, please contact us to rearrange delivery.

If there appears to be any sign of damage to the packaging of any products in respect of which a signature is required on delivery, please make a note to this effect beside your signature.

Please be specific about damage and do not simply state ‘unchecked’.

Please wait
