Amazon Astore Site Intergration - Use Your Own Domain Name

I have been toying with aSensibleStore.com in order to add extras to an amazon astore.
There service is ok and you may want to check it out.
What I wanted though is an astore that had my domain name, without doing any framing or 301 redirects.
What I came up with is this -
http://www.flavour-shaker.co.uk/ which is based on the new Jamie Oliver device of the same name. It is essentially an astore included in my domain. This is useful for two reasons.
I can further control Layout and extras (extra links - adwords rss feeds etc) and urls are resolved to my domain - http://www.flavour-shaker.co.uk/jamie/flavour-shaker-21/detail/B000INFF9A/
I can track traffic using google analytics or server logs
WHen a product is added to the shopping cast though the site jumps to the astore.
The script is very simple but powerful.
I will be tweeking the script and will eventually post it here. So if you want this free powerful script just subscribe to this blg using your feed reader
