I've found one new link offering a free Harper's magazine subscription. Plus these two older links (here's the first and here's the second) also seem to still be working.
This is not to be confused with the usual free Harper's Bazaar, which I totally didn't do all day today, no siree.
So what's Harper's about?
Harper's Magazine is a renowned American monthly magazine known for its long-form journalism, essays, and commentary on politics, culture, literature, and the arts. Its articles are known for their high-quality writing and thoughtful analysis, appealing to a readership interested in deep, reflective journalism.
This complimentary 1-year subscription is a $10 value and you don't have to opt into any of the “bonus” offers presented after submitting your mailing address.
It's been three years since I found a Harper's freebie, so be sure to snag this now if you're interested!
