There are thousands of e-commerce solutions available ranging from a few hundred dollars to implement scripts, to out of the box solutions in the thousands, to custom solutions in the tens of thousands?  I'd like to know what network participants think is the best approach in e-commerce and what examples exist of those approaches?

For my part, my firm Polar Design recently redesigned a Marble and Granite Cleaning e-commerce site that led to a 30% boost in sales right after launch.  We wrote a case study about this e-commerce solutions as well that might be of interest.
