Items in stock are always at the price shown on our website. Our system cannot work any other way. Your postcode is Inverness which is the Scottish Highlands, this is why you fall into our 'Highlands and Islands' postal category. We don't profit from delivery, we charge what it costs, so if you were charged a lot for delivery that is due to the courier and beyond our control. Your order is a back order and you have been advised via email of expected delivery dates (this is built into our system - please check your junk folder if you haven't seen that mail). Our apologies for failing to satisfy you but these claims are a little unreasonable. We hope to get another chance to show you that we normally offer excellent service. Regards, Studiospares.
