I have received a few different magazines from this site – FREE, no credit card, no agreement etc. I have received healthcare magazines, and small biz magazines as well as some computer magazines & Financial/biz type magazines. I DID have to answer a few questions to qualify. Im a nurse, run a small business with my husband and my husband is in the Finance Field, so Im assuming that is why I qualified for those types of magazines! Anyway, its worth a try to see if you qualify for the magazines your interested in! Head over to the site and check it out!
