4.1 The price of any Products will be as quoted on our Site from time to time, except in cases of obvious error. 4.2 These prices include GST but exclude delivery costs, which will be added to the total amount due once you have selected a delivery service from the available options as set out in Delivery Information. 4.3 Prices are liable to change at any time, but changes will not affect orders in respect of which we have already sent you a Dispatch Confirmation. 4.4 We cannot complete your order until you have paid for it in full. Payment can be made by most major credit or debit cards by completing the relevant details on the “Payment Details” page. 4.5 By using a credit/debit card to pay for your order, you confirm that the card/account being used is yours. All credit/debit card account holders are subject to validation checks and authorisation by the card issuer. If the issuer of your card refuses to authorize payment we will not accept your order and we will not be liable for any delay or non-delivery and we are not obliged to inform you of the reason for the refusal. We are not responsible for your card issuer or bank charging you as a result of our processing of your credit/debit card payment in accordance with your order. 4.6 Our Site contains a large number of Products and it is always possible that, despite our best efforts, some of the Products listed on our Site may be incorrectly priced. We will rectify any such errors as soon as possible once we become aware of them. If a Product’s correct price is different from the price stated on our Site, we will normally, at our discretion, either contact you for instructions before dispatching the Product, or reject your order and notify you of such rejection.
