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 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.[162] 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.[citation needed]
“Amazon respects its employees’ right to choose to join or not join a labor union. Amazon maintains an open-door policy that encourages employees to bring their comments, questions, and concerns directly to their management team for discussion and resolution,” Robinson said. “We firmly believe this direct connection is the most effective way to understand and respond to the needs of our workforce.” (The 1935 National Labor Relations Act protects workers’ right to form unions.)
It’s hard to predict exactly what Amazon’s new rates will mean for those participating in the program, but there’s plenty of reason to be nervous. The most immediate change will be the end of Amazon’s “variable standard program fee” rates, which gave sites a higher cut as they drove more business to Amazon. The scale ranged from 4 to 8.5 percent, depending on how many products visitors bought in a given month. Robey says she never had trouble selling enough products to earn an 8 percent rate.
Thanks for your point for point description of what has worked for you. You have certainly given credibility to testing your results. Doing the technical aspect of setting the structured sites and e-mail marketing has been challenging for me. You have clearly described how the more sales you make your percentage goes up and you make more money. Apparently there are tested formulas that work for Amazon sales and getting people to Amazon sounds like a winner.

The same goes for when Amazon starts selling a product against you. The best retail arbitrage opportunities are when you're competing against other third party sellers – because it's a level playing field. However, if Amazon decided that Skyline Chili sells so well that they want to start buying and selling it directly, they'll probably have a retail price similar to your local store. 
In July, when workers in Spain, Poland, Germany, Italy, and France used Prime Day to strike and rally, a former Amazon warehouse worker named Seth King from Chesterfield, Virginia, told me that the warehouses were the type of place where “they work people to death, or until they get too tired to keep working.” He left after two months because the job had brought him to “the lowest point in my life” and that he felt “I couldn’t work there and maintain a healthy state of mind.”, Inc., doing business as Amazon (/ˈæməˌzɒn/), is an American electronic commerce, cloud computing, and consumer electronics company based in Seattle, Washington, that was founded by Jeff Bezos on July 5, 1994.
