Reward Survey offers $20 in reward points for taking their online survey. You can then use those points to get a selection of magazine subscriptions for free, including Wired, W, Inc., and more. That's tied with our mention from four weeks ago as one of the best deals we've seen for such a wide selection of popular magazines. A couple of best bets:

Wired Magazine 1-Year Subscription for 15 points (12 issues, low by $20)

Shape Magazine 2-Year Subscription for 20 points (24 issues, low by $32)
