What is Amazon MWS Subscription API and SQS?

Amazon MWS Subscription API released in the month of August 2013 to provide the sellers ability to reprice the items more rapidly than the older 'Products API'. This is useful for many of you who use the automated repricers as this new feature works based on the SQS(Simple Queue Service) triggers received within the lowest 20 offers for each item repriced.
New Subscription API would provide you the ways to filter your repricing strategies with quick efficacy as the market moves. Hence, you can make use of features like detecting the competitors as Featured or non-Featured (which was the main drawback of Products API) or ignore the competitors, reprice based on your position in offer listing page (or of the competitor) etc.
As the name suggests this new API is available at subscription from Amazon, and is not free for you. You will have to create an account with, input your credit card details, and enable SQS under 'AWS Management Console' to subscribe to this feature. Depending on the number of active SKUs repriced, Amazon may charge a fee upto $25 a month. Generally for the SKUs count less than 10,000, it's free. Actual cost of this service depends on the number of XML triggers received per month.
