Goodreads is a "social cataloging" website founded in December 2006 and launched in January 2007 by Otis Chandler, a software engineer, and entrepreneur, and Elizabeth Chandler. The website allows individuals to freely search Goodreads' extensive user-populated database of books, annotations, and reviews. Users can sign up and register books to generate library catalogs and reading lists. They can also create their own groups of book suggestions and discussions. In December 2007, the site had over 650,000 members and over 10 million books had been added. Amazon bought the company in March 2013.
Some other large e-commerce sellers use Amazon to sell their products in addition to selling them through their own websites. The sales are processed through Amazon.com and end up at individual sellers for processing and order fulfillment and Amazon leases space for these retailers. Small sellers of used and new goods go to Amazon Marketplace to offer goods at a fixed price. Amazon also employs the use of drop shippers or meta sellers. These are members or entities that advertise goods on Amazon who order these goods direct from other competing websites but usually from other Amazon members. These meta sellers may have millions of products listed, have large transaction numbers and are grouped alongside other less prolific members giving them credibility as just someone who has been in business for a long time. Markup is anywhere from 50% to 100% and sometimes more, these sellers maintain that items are in stock when the opposite is true. As Amazon increases their dominance in the marketplace these drop shippers have become more and more commonplace in recent years.
The main con is obviously the cold, crowds, and chaos. But just because Black Friday traditionally means in-store shopping, doesn't mean that many retailers won't offer sales online. Last year, online sales hit 19.62 billion over the five-day period from Thanksgiving through Cyber Monday. So if you don't want to wake up in the middle of the night to battle crowds and wait in long lines, check with your favorite stores to see if you can do it all from the comfort of your home.
