These magazines will come, i have used this company in the past. In my experience they do share your information though, I get junk mail that has been obviously sourced from this place a few times a year.
I will tell you that it is at the sole discretion of the publisher -- I signed my husband and brother up for EGM and I expected my brother not to get it after I found out (after signing him up) that they don't accept students... But I thought my husband would get it -- however later I rec'd an email from them saying he was declined.
I've gotten magazines from these guys in the past...so went through and signed up.
On a side note I noticed someone on here got a free autoweek subscription. It appears to still work so now you can get a free autoweek sub too. I would use another email address though.
