I am a newbie and I would be interested to know what you have purchased so far. I tend to concentrate on freebies and keep away from “fancy products”. So far I have bought the following:

Aweber autoreponder
Hostgator
2x domain names
Subscription to a mentor
Market samurai (my biggest investment to date)

As a whole, the start up costs in IM are still relatively low. Would love to hear your stories
