DiscountMags offers a Popular Science Magazine 1-Year Subscription (6 issues) bundled with a Wired Magazine 1-Year Subscription (12 issues) for $24.99. Coupon code "DEALNEWS" cuts it to $7.99. That's tied with our mention from last month as the best price we've seen for this bundle. (It's also the best deal now by $24.)
Of note, you can purchase up to a 3-year subscription at this discounted annual price.
