Let me tell you that I have nearly tried every amazon affiliate plugin out there, and nothing has pleased me more than this wonderful plugin.
Some of the unique features:
-This plugin DOES NOT slow down your website.
-Powerful localization support.
-Custom templates, and modules (extras) for added functionality. Can be customized to the last bit.
-Product image and thumbnail size customisation, and yes, alignment is possible too.
-Product caching, short-code caching and pre-fetching available.
-Did I mention that the developer of this plugin,Paul,is very active and provides EXCELLENT support! I am very grateful to Paul for his quick and accurate responses.He has been very very helpful.
So, without a second thought, grab this plugin if you are searching for an Amazon Affiliates plugin. And seriously, I can't imagine why some users have given this plugin less than 5 stars!
I recommend all to try this plugin and rate it accordingly (I am sure you will love this).
