We are unable to advise the precise postage cost until we have received the order.
Our postage is calculated fairly according to the destination and weight of the order including packaging. We source the least expensive method for each customer (unless they specify the order is urgently required). All orders, including carriage, are plus VAT unless you are outside of the EU (or if you have a VAT number within the EU.)
Obviously we would not presume to take the money from your debit or credit card without providing you by email the carriage amount and the opportunity to accept or decline. The website ordering system does tell you that carriage will be advised. An email response is sufficient.
We do not have a minimum order charge and our minimum postage is £2.00 + VAT.
