I have spent the last few months in developing a new online store based on Magento’s eCommerce Solution.  Graded Labs now offers learning capsules, online support and bulk discounts on tokens.  Developing with magento was difficult and cumbersome at first, but then after you get the hang of things, it turns out to be a solid shopping cart framework.   Overall, magento is looking pretty promising as a extensible framework, which is based on the Zend framework.

Anyway, check out the new store at www.gradedlabs.com.
