New User with a Question - Please Help

[Guest]

Hello, I have been all over the forum looking for the answer to my question, but i have not found it.......I am sorry if the thread does exist.

 

here is my question:

 

I would like to have a membership(no fee) based sited where customers can register with their CC's and then when a product arrives that fits their criteria it is billed to them and shipped out automatically. How would I go about the billing structure for this, since it is not a one time purchase or a conventional monthly subscription based recurring billing.

 

I would really appreciate help on this.

 

Thanks in advance!
