Everything here are just examples, but the idea is real. So let's say I'm in the niche of dog training. I create 2 products(1 front-end and 1 back-end): Book A and Product B. I'll sell Book A at a cheap price, and then offer Product B as OTO. Book A is just a normal one-time purchase, but Product B is different. You have 2 choices: (a) Pay a one-time fee of $97 and get Product B fully. (b) Pay $27/month for 3 months($81 total) to get Product B in smaller chunks, which will be sent weekly(promotes taking action). Product B is a screenshot-intensive, step-by-step program that helps you do something. Default mode of delivery is by sending assignments weekly to promote taking action, but you can choose to instead download Product B(complete) instantly by paying a premium($16). Would this idea succeed? Would YOU pay for something like this in an area you are interested in? Thanks for all and any feedback!
