A Note About Customer E-mails

We seem to have an increasing number of delivery failures with the automated order acknowledgement e-mails form our OpenCart shopping platform. Please ensure you use a valid e-mail address when registering or ordering and if you do not receive an acknowledgement within a reasonable time please check your spam and junk mail folders. If you still cannot find an acknowledgement please contact using our regular e-mail address.


Due to the greatly extended shipping times for International orders, we are now only offering tracked/signed service. This provides reassurance for both ourselves and our customers that orders are in transit.

Deliveries to some parts of the UK seem to be taking longer than normal, so please be patient. All our UK orders are sent as First Class Small Parcel.
