Installing Amazon Product in a Post
Before installing the plugin, head to aws-portal.amazon.com/gp/aws/developer/account/index.html and sign-up for an AWS (Amazon Web Services) key; this is vital for using the plugin. If you already have an Amazon account, this should be pretty simple to do; otherwise you will need to sign-up.
After signing up to AWS you will receive a confirmation email message. Read the message and look for the link relating to your Access Identifiers, and click it to open the page where your Access Key and Secret Access Key can be found.

Leave this page open and then head back to your WordPress dashboard. Open the Plugins page, search for “Amazon Product in a Post" and Install. After installation, select Activate plugin and find the Amazon PIP menu on the left-hand side of the display and select Amazon PIP Options.
In this screen you can add your Amazon Affiliate ID, the Amazon Public Key that you just created and the Amazon Private Key which is hidden on the same screen as the public key. Save your information, making any changes that might be required based on your location and language, and then open the Amazon PIP page (note also that CSS for the Amazon Product in a Post plugin can be adjusted from this page).
From the Amazon PIP page you can create a product listing which can then be added into your blog, using the Amazon item’s ASIN number (this can be found in the item URL – for instance a Kindle device has this URL: http://www.amazon.co.uk/Kindle-Wireless-Reader-3G-Wifi-Graphite/dp/B002LVUWFE and the ASIN is B002LVUWFE) and by adding a description and selecting a category for the post to appear in.
Just select Publish from the drop-down menu and hit save, and your Amazon post will be added to the selected category and published to your blog!
