If you link to Amazon products on your blog a lot, you need the EasyAzon plugin. It will save time and effort by looking up ASINs, formatting the affiliate link for you, and inserting it directly into your post. With just a few clicks, you have your choice of text or image links set up. This has literally saved me hours of work! I love this plugin so much, I bought the developer rights and will install it on your WordPress site for only $5. (Buying direct from the publisher will cost you $47.) Comes with easy how-to videos to walk you through set-up and inserting the Amazon affiliate link into your post, plus my assistance if you need it!
