Amazon.com is a leading online retailer of products that inform, educate, and inspire. The Amazon group also has stores in the Canada, Germany, France, Japan and United Kingdom. Because we exist "virtually" on the Web, we have unlimited shelf space and can offer a selection of over 17 million titles including over 13 million Book titles and over 1 million music titles. Compare that to a typical physical-world book superstore, which carries around 170,000 books, or a typical physical-world music superstore, which carries around 34,000 CDs.
Titles have different availabilities simply due to their demand, proximity, and availability to Amazon.com. We also source our products from various distributors. The availability on products we obtain from distributors may vary according to whether the distributor has the product in stock or not. If a title is listed as out of stock or unavailable, it means that it is not currently available to Amazon.com or not in stock through our distribution channels. However, you may still be able to sell out of stock items through our Marketplace feature.
Our sales rank is just like a bestseller list, except instead of listing just the top 50 or so titles, it includes millions! The lower the number, the higher the popularity for that particular title in comparison to other items listed. Items are ranked within their product category only, so a book, CD or DVD ranked at Number 1 is the best-selling book, CD or DVD at Amazon.com, but may not be the overall best-selling item. Sales rank data is calculated hourly. While we cannot provide specific information about our calculation formula, Amazon.com Marketplace sales are also included in the calculation. Please keep in mind that our sales rank figures are simply meant to be a guide of general interest for the customer and not definitive sales information for vendors - we assume you have this information regularly from your distribution sources.
We don't provide sales information to vendors at this time due to the competitive nature of our business. It is recommended that authors/artists/actors contact their publisher/label/studio, or publishers/labels/studios contact their distributors, for more information concerning the sales of their titles.
At Amazon.com, it's up to you to make your titles stand out on our virtual shelves. You have the opportunity, using descriptive content and images, to personally hand-sell your titles to customers and persuade them to purchase. Following are the most important pieces of information you can add to your product detail page.
Generally, to qualify for head of household filing status, you must have a qualifying child or a dependent. However, a custodial parent may be eligible to claim head of household filing status based on a child even if he or she released a claim to exemption for the child.
