Zag; I would like to add that I came across activshopper from a friend, downloaded it, used it for a bit, and because I've done a little online investing over the last few years researched the company and THEN I bought the stock. I found that Activshopper is no doubt the best shopping search tool out there, actually, in my opinion, the only shopping search tool out there. So in my case I did not download the software to try to increase my investment value, however, I invested in a company when I became impressed with their product.
