For its Prime members only, Amazon offers 4-month subscriptions to up to three eligible magazines for free. That's tied with our October mention and among the best Prime freebies we've seen. (For further comparison, a 1-year subscription to most of these magazines costs $10 or more elsewhere. Choose from titles such as Wired, GQ, Popular Science, Saveur, and Glamour. Deal ends April 8.

Of note, be sure to cancel your subscriptions before your 4-month trial is up to avoid being charged a renewal price of $9.99 per magazine.
