need help w/ how to set this idea up

[asdfasdfxp]

Hi,

 

I am going to open a study notes downloading store.

People can view all my study notes, but when they click to download, it jumps to the registration page.

If they are paid users, they can just input user name and password to continue downloading.

If they are new customers, they have to register a new account and choose to pay as a member first, then they can download.

 

so in this case, I don't need the shopping cart.

 

Any help and suggestions will be appreciated.

 

Thanks,

 

John
