ABSTRACT
Carl was browsing the internet when he came across a site, run by OperaClassics, which was offering a set of CDs of the complete Wagner Ring at the price of £120. In accordance with the information on the site, Carl immediately sent an email to OperaClassics ordering a set of the CDs, and giving his credit card details. About 30 minutes later he found another site, run by DirectOpera, which was offering the same set of CDs for £75. He selected this set and then moved to the website’s ‘checkout’ page. Here he was asked to fill out a form, giving his details, including his credit card number. He was then presented with a page setting out the details of his order and asking him to click on the ‘confirm order’ icon if he wished to proceed. Carl did so. He then immediately sent a second email to OperaClassics cancelling his previous order. Five minutes later he received an email from OperaClassics in response to his original email, confirming that his order was being processed.
