virtually every language utilizes shopping cart demos/tutorials in which to learn.
The only flashbuilder/flex shopping cart I found was a rather old, flex 2 flexcart application.

With such a cool, feature rich set of components, I would like to see FlashBuilder corner the RIA market.
Unfortunately, I am new to Flex/Flashbuilder and my resources are limited to what I can find on-line.

For the sample for Flex, try
