Please note that multiple board orders may not give a saving on shipping - the value of a shipment of multiple boards exceeds the cover provided by standard postage costs, and requires a more expensive tracked service.

Also boards will not be supplied zero-rated for VAT within the EU to VAT registered customers.
This requires a different shipping method that costs more than the potential saving in VAT.
