I spent way too long hunting for a real DVDFab discount last year because their lifetime license is just brutally priced, and the only place I actually found a working coupon was couponcodes.store — took about 15% off, nothing crazy but it was real and the license still works over a year later. What surprised me is that
DVDfab themselves almost never drop the price on lifetime plans, so those third-party aggregators end up being the better bet, not the official site. Just pay attention whether you're buying lifetime or subscription because their product naming is confusing as hell, and always use PayPal in case something goes wrong.
