Well thanks everyone, especially to "Foxette in Sox", who drew my attention to the fact that living on an island could prove to be difficult, and in not understanding that an actual courier would be dropping the products of (all the way from Sydney to Queensland), it was then that I realised the difficulty I was having with the company in terms of what appeared to be incorrect postage costs (and they were caught out as well, with not having had my area listed in their postal quotes).  In the end, they must have been estimating how far away we were living away from the mainland, and quoting me on that alone, without realising there is no bridge, and therefore, no courier would have been able to deliver the goods anyhow.  Upon realising the mistake that we both had made, they were more than happy then to cancel the transaction because of that.  So thank goodness I did not have to deal after all with the electric shock element, only the shock of the postage costs!! I think we both have learnt a valuable lesson from this, and I thank you all for your advice.  You have all been too kind:)
