I've got an idea here but I'm not sure how to go about it. What I was thinking about is releasing the price of a product before it's released. I find this to actually be common practice with companies releasing whatever it is they're selling, but I'm not sure if this may be the way to go about it. For example, long before gaming consoles are released, the price is put everywhere.
I was thinking that releasing the pricing information before the product launch may work for you in a good way since you can probably get a better idea of how many people will be interested in buying it before it's released. Most will probably scatter once they see, so you'll be left with only serious people who are with you on what you'll be releasing.
What would you do?
