as you already know and see everywhere, a lot of people advertise their content or WSOs like the title of this thread.
This gives me the following questions:
1. how do they know or believe their content is worth $$$$ e.g. $ 947 ?
2. why do they choose to sell it for $ 9 and not $ 19 or $ 29 ?
3. would you return the WSO if the value is not $ 947 but the actual $ 9 ?
4. Is there a chart or statistics to see what you deliver is worth? e.g. if I have an offer about Getting Traffic, what could you say is it worth?
5. How should anyone know what it is really worth, if all the WSOs are a secret until you buy them?
...or is this just a simple (stupid) marketing trick to get people buy their product??
Answers are very appreciated
