I'm working on a news site built with Wordpress, and I now want to add a page for subscriptions. This will be paid subscriptions for the printed paper that people can get delivered to their home.
My question is: is there a Wordpress plugin already created for this (free or paid)? I wouldn't really want to re-invent the wheel. Maybe I could somehow use one of the many Wordpress shopping cart solutions?
If not (which I suspect to be the case) how would I go about doing it on my own? I have no problem coding this up as a standalone application. I'm just not sure of how exactly to integrate it into the Wordpress admin area.
