I would never recommend buying leads from GDI or most any other company for that matter. You never know where they came from. The CD's are fine as long as you put them in the right places.
I generated six sales recently without paying a dime for my leads because I know where to find unlimited leads for free. I know exactly who these people are and they are much more receptive then bought leads.
There is a community where all you have to do is join GDI in their downline and you will be able to receive free internet training for life. This is where I learned to generate my own leads for free and there are other classes like website promo techniques, blogging, Outlook Express. They even have a class for the GDI back office to help you get your paperwork into the company so you can get paid.
Right now all the classes are for free but they are going to start charging soon and only some of them will be accessable with the GDI sign-up. It will cost more money for the other more advanced classes. Most of my sign-ups already had GDI accounts but signed up again when they saw what else they could get.
It's a great pitch. "Sign-up for GDI and get all this other stuff for free."
