From where can I buy Chess Programs?

Say, I want to buy a Chess Program where will I search for them?

I am asking this Question because I want to know where do people go to
buy Chess Programs. Then I will Sell GetClub Chess over all those
places.

I went to amazon.com and found lots Chess Program were sold there. I
wanted to sell GetClub Chess. But it asked me to search items from a
list and I found all Chess Programs Listed there but GetClub Chess was
not listed. So I was unable to sell GetClub Chess at Amazon.com.

How can I sell a new Product at Amazon.com? As it only asks me to sell
products already listed on their site.

I would like to sell it at Ebay.com but I could not understand how to
sell GetClub Chess there.

Can Someone give me list of Sites which sell Chess Programs. So that I
too sell my GetClub Chess over those places.

I will give 10% commision to the site selling my Chess Program.

Which are the Top Sites where I should sell the GetClub Chess?

Because till now I was interested in developing the Program. Now I
want to get Profit by selling it. My Target is to sell atleast 1000
copies a month.

Please suggest all places and techniques that will help me sell
GetClub Program to new Customers.

Bye
Sanny
