I do a short survey 1 or 2 times a week for RewardSurvey
The surveys take maybe 5 minutes, I've never been disqualified for one, and they are worth $20 in magazine money.
Different magazines are available at different times.
Sometimes I cash in right after a survey if there is a magazine I want and sometimes I just leave the rewards in my account,
I think I've been doing them about 3 months and I now have free year long subscriptions to all these magazines shown above as well as Forbes, New Yorker, Garden & Gun and Real Simple.
Reward Survey sends me an email about once a week and that's when I do a survey.
And. No, I don't read all of these but I share them with my family.
If you like magazines, try Reward Survey.
The magazines really do come and they have no charge.
