Just a reminder, that these "I will buy your method threads" are cockroach threads. If you have a minimum of social empathy, you know that these threads are honey pots. So stay away from these vampires and earn your money by your own methods!
Step 1) "I'll buy your method!" Step 2) "Oh no thanks I already know that method, I can't pay you for it" Step 3) Profit?
I am interested in this, i can see the benefit for both parties. First if the seller is clearly making bank, then it would be hard for any reasonable buyer to claim they already know the method. Second it may be more profitable for the seller to sell his method to one person instead of creating an ebook that always has the potential to saturate certain method. My belief that if both parties are honest then buying a persons method can be great.
There is only one point in selling methods: You don't have the balls to use them or it is outdated. First one is for honey pots. So don't think about it. It's the same like selling 'profitable' websites on flippa vice versa. Why should somebody sell something, he's earning money from. Imagine that a philippine, hehe... like Rick Latona is enslaving.. has an idea, which could make thousands, but atm he couldn't get the fortune. Selling it and watching others to make the big bucks instead of waiting, until his time has come, will kill his soul in the long run. Better he test it and earn some money and share it then here or with his buddys for free, when the time has come.
