Hi all - I was trying to download a sample book from Amazon to run under Kindle for PC, but inadvertently clicked a poorly labeled button, that turned out to be the purchase button. because my account details are stored on their database, I was immediately charged for the book. This is only £0.99, but wanted to give a be careful warning for others trying to read free samples ahead of buying, and to ask if anybody has managed to read samples successfully without, or before buying? It seems a bit unclear to me which link or button to click for this, as they are not so clearly defined - Andy
