1. Clicking onto any of the links above will not commit you to buying anything. It will merely enable you to peruse & compare the different new & used prices for this book from the different Amazon sellers (called "Marketplace"). You will be able to click onto your "Back" button (upper left of your monitor) a few times to exit the Amazon site & get back to our website, without being committed to buying anything.

2. In order to purchase anything, you will need to click onto an additional "Add to Shopping Cart" button, then click onto "Proceed to checkout", & then give your credit card information. You can add as many books as you wish to your Amazon cart (even from different pages in our website), before finalizing your purchase by clicking the "Proceed to checkout" button & entering your credit card information. There is a "delete" button under each book you add to the "Shopping Cart" with which you can immediately or later delete it from your shopping cart if you wish.

3. Amazon has a secure encrypted (https) payment section of their web site so credit card purchases from them are safe. You pay Amazon alone & then Amazon pays their "Marketplace" sellers, so your credit card information goes only to Amazon, not to any of the "Marketplace" sellers. It's a good system.

4. Canadian $ (CDN$) links are in the pictured boxes above. United States $ (US$), & United Kingdom pounds (GBP) links to the same books are given as "text" links below the pictured boxes.

5. In the pictured boxes above, clicking onto the "Buy from ..." button will take you to the new price of this book when bought directly from Amazon. Clicking onto the "Best Price" link, above the "Buy from ..." button in the pictured box, will show you all of the varied new & used prices for this book from the different Amazon sellers (called "Marketplace"). Generally the "Best Price" link is the better way to go as it also includes a listing of Amazon's new price for the book (you will be able to find Amazon's new price listing by checking who the seller is for each listing).

6. Clicking onto the "title" link of the book in the pictured boxes above (above the "Best Price" link) will enable you to read a description of the book, & sometimes product reviews of it by different people. There will also be a "View product details" link at the top of the "Best Price" listings page, which will take you to the same description/product reviews page.

7. Amazon sets a fixed price for the shipping costs they or any listed "Marketplace" seller can charge, regardless where the listed seller is shipping the book from. Amazon itself however, charges a bit lower shipping rate than it requires it's "Marketplace" sellers to charge. More importantly, for the purchase of more than one book, Amazon charges a much lower shipping rate for each additional book, whereas "Marketplace" sellers charge their fixed shipping rate multiplied by the number of books you purchase. Amazon's multiple book discount in shipping can thereforesometimes outweigh the benefit of choosing the lowest "Marketplace" price.

8. Amazon also offers Free Super Saver "Domestic" shipping if you live in Canada for .ca purchases, live in the US for .com purchases, or live in the United Kingdom for .co.uk purchases, & if you buy directly from Amazon (not from the varied "Marketplace" sellers), & your total order's value is higher than $39.00 CDN, $25.00 US, or 15 GBP. This can often outweigh the benefit of choosing the lowest "Marketplace" price.
