Reward Survey offers $20 in reward points for taking their online survey. (Compared to what we've seen from Reward Survey in the past, it's a very short survey.) You can then use those points to get a selection of magazine subscriptions for free, including Golfweek, Inc., Cigar Aficianado, Fitness, and more. Some best bets:
Details Magazine 1-Year Subscription for 10 points (10 issues, low by $8)
Inc. Magazine 1-Year Subscription for 10 points (10 issues, low by $10)
Wired Magazine 1-Year Subscription for 15 points (pictured, 12 issues, low by $20)
Wine Spectator Magazine 1-Year Subscription for 20 points (15 issues, low by $50)

There's a less expensive way, and then there's the way that works for you. The two may not be the same.
