Please ensure payment is made within 72 hours of purchase. Failure to do so will result in the product being re-listed & an "Unpaid Item Case" opened with eBay to recover our fees. Postage costs are automatically discounted by eBay for combined purchases. Please email us BEFORE YOU PAY requesting a new invoice if you have NOT received discounted postage. We will then check & re-send a new corrected invoice total. IMPORTANT - We can NOT make invoice corrections once payment has been made.
