Call me crazy, but I don't understand the question. The fastest way to create an astore is to go to astore.amazon.com and make one.
I make 1 store not over 10 minute. but we have niches keyword. after that we can make astore very easy.
Thanks guys and girls. I have learned to create them very quickly. And they can earn you money. I use ppc.
If you have bought associate-o-matic, you probably can have one shop in 10 minutes with full features!
