We combine p&p/shipping.
If buying more than 1 item, please add all the items to the shopping basket/cart before you go to checkout - the combined postage discounts will be applied automatically at checkout but if in doubt please request an invoice before you pay.
Non EU Customers will receive a refund for VAT (sales tax) as they are exempt from it.
I do refund overpaid postage but have to deduct the 10% ebay charge on the postage as they refuse to refund their share!
Sellers have the right to set their own prices independently, but some manufacturers place restrictions on how these prices will be displayed or communicated to others.
