Killer Commissions From High Ticket Amazon Products – Amazon Treasures
Product Price: $9.06
The product certainly is valuable, but that value diminishes rapidly with each copy sold. Unless you can say you're limiting it to X number of sales, I can't buy it - because every copy you sell encourages direct competition against each of those who have already bought it.
When I discover niches, I try to keep them quiet, not publish a list for (hundreds/thousands) to compete against me.
If you come out with another similar list with a limited number of copies to be sold, I'll gladly pay a premium of many multiples of the current list price.
