Shipping And Packaging

Orders will usually be shipped with economy service (2-3 working days), orders of 3 packs or more will be sent with our dedicated overnight courier and will require a signature to confirm receipt. If you have selected economy service and you have not received your parcel within 5 days, please contact us. Please note that after your order has been dispatched, you may receive a text message from our parent company Safelincs stating that your goods have left our warehouse.

Please check the status of your package immediately before signing for receipt of the goods. If you see damage on the outer packaging this must be noted on your copy of the delivery note and on the copy of the carrier, otherwise you might not be able to receive a replacement or refund from us. You can also refuse damaged parcels without signing for these.

If a customer is not in when delivery is attempted, the delivery driver/postman will leave a card with details of the local depot. Please ring the stated telephone number if required to do so on the card. Please note if the parcel cannot be delivered after several days and has to be returned, we reserve the right to charge you a second delivery fee for re-delivery, should you still wish to receive the product. Alternatively, we might refund you and cancel the order.

If you add special delivery instructions such as "please leave parcel in porch if not in", we cannot provide you with a proof of delivery should the parcel go missing. We will however provide a proof of shipping if requested. You are responsible for any losses suffered as a result of a parcel being left in a location at your specific request.
