Books, like children, require attention for long periods of time and take up valuable space, whereas magazines can be quickly read and stuffed into cereal boxes when not in use. Take a stand against roomy reading material with today's Groupon: for $10, you get $20 to put toward your choice of magazine subscriptions from BlueDolphin.com.

An online supershop of readables, BlueDolphin.com offers more than 1,000 magazine titles spanning nearly every imaginable genre. The site's mags are supplied by publishers at already discounted prices, allowing readers to get their literary fill without hocking their grandmothers' priceless porcelain flyswatters. Browse through the selection of titles available for $20 or less to find a year's worth of affordable reading, or choose your favorite category—from news and sports to computing, cooking, and gambling—to line up a suitable bedtime companion, such as Good Housekeeping, Rolling Stone, or The Beer Connoisseur. To help ensure word diets stay balanced, BlueDolphin.com also streamlines the subscription experience with MagTracker, a free online service that makes keeping tabs on your mags easier than bilking an aging schnauzer out of his 401(k).
