I have made a number of Appsumo purchases, but this is my first review. I don't know how long this lifetime deal will be available, but I would suggest anyone grab it while you can. Viral campaign platforms are complicated and good ones are hard to come by without spending an arm and a leg or getting severe limitations. I have others, but when I stumbled upon this one, it had pretty much all the features you need, and then some, and the lifetime deal is incredible. There are still some minor bugs and issues to be resolved, and some improvements coming down the pike, but James seems very committed to tackling everything issue and constantly improving. He is extremely responsive to support questions.
If you are serious about creating campaigns and driving traffic you should get the full lifetime stack while you can. I imagine it will outshine the other much more expensive platforms out there very soon. And will then be priced accordingly.
