It is just a mistake of zero the price is 10$ .
PM for proof .
Even you, seems to be confused with the price. So how much really it is? Anyway, what is your reason of selling? If a person can sell it for $1,000 or even $10,000 as you have mentioned
here or $15,000 as stated in the title, why don't you sell it yourself with that price? Something's wrong with that, right? Very unusual for people to sell a thing in a very cheap price and let others earn from it.
Changing price and cheapest price of a particular method which generates you a good income per month which really tells us that its a total scam. If these method is possible i would keep it on myself and wont sell it to other just like other members said here i would use it as long as i can since im making money and OP mentioned 10$ price method for a 15000/month method? Unbelievable.
