For the better understanding of AWS you can use Jaaps Free Amazon PHP Scripts
Jason Levtt has written a book the awsbook.com AmazonLib is a PHP library for use with Amazon.com's E-Commerce Service 4.0 and Seller Services (AIMS and Merchants@). It includes a useful XML parser and scripts that illustrate the Amazon APIs. The scripts are described in a book: awsbook.com
well, at the moment we have some Nuke- and osc2nuke-Modules with Amazon-services - featuring a bunch of nice and powerful Amazon-services - here a roundtrip:
- the Amazonia-Gallery: a powerful PHPNUKE-modul - based on the NukeAmazon-Modul from preciogasolina.com. The Amazonia-Gallery is based on Amazon Gallery 2.xx of EJDiaz. EJDiaz from preciogascolina.com works permanently on his NukeAmazon-modul (Demo)
