Not a scam, a b2b magazine. I have dealt with them in the past; these kinds of companies are sometimes mistaken for telemarketers but listen to their pitch - its just a magazine. The worst thing you have to deal with is an unwanted call if you're not interested. I am sure there are some scams with a similar approach that I guess must take add dollars and abscond, but that wouldn't last long and probably wouldn't make much money. This is true for almost every service industry - think Bernie Madoff for a high level example; doesn't mean all Financial professionals are crooks.

call says he is from US Builders Review.  Seems like a scam
