Alvenda is taking a different approach to e-commerce. Rather than using advertising to drive traffic to a webstore, they are enabling purchases directly in the ad, without leaving the user's current website. This effectively allows a webstore to have a presence on blogs, social networks, and other places where you see traditional advertising. This "distributed store" takes shopping to the customer, instead of the other way around. Its an interesting concept that you can test drive for Mother's Day.
