Step 3. In the window that appears, you will see all your recent orders.
It might be that you ordered the book a while ago. To get the book to show up in the order list, either search for the title, or click Filter.

Step 4. If you chose to search for the title, you will be presented with the search results.
Click on the title of the book.
You may proceed to step 5.

On the next screen, click on the title of the book.
Step 5. On the page that appears, click on Write a product review.
