To get a free year subscription to Martha Stewart Living Magazine.
This is how I get the majority of my free subscriptions. You don't have to enter billing information, which is the only way I'll sign up for 'free' subscriptions. You just have to fill out a small survey.
If you are worried about spammy email, my word of advice is to have a separate spam email account just for things like this. I have an extra AOL account for this purpose only. It always makes me laugh when people will refuse to sign up for deals like this because of fears of spam email. Don't use a really important account! Simple.
Anyways, like I said. This is totally legit. I've been getting TV Guide, Better Homes and Gardens, Hallmark and Travel & Leisure from this site for the past year, so feel free to do it if you want Martha for a year.
(thanks MoneySavingMom for this hot tip!)
UPDATE: It seems the offer is over now, sorry if you missed out!
