Please note that our shipping prices are a higher than it would cost to send a normal parcel via the post, the reason for this is because any product that contains chemicals must be sent and packed as per the "hazardous goods" regulations, and be transported by a carrier that is licensed to be able to transport. we are unable to send by regular post as it is now a criminal offence to send undeclared hazardous goods.
