I plan to start selling subscriptions in some of my sites, and also i plan to start charging for ads posting in other sites i own.
I have a paypal merchant account and i have read some of their features.
I also have a website with zen cart and i like the payments admin module, very easy to integrate with paypal and other payment gateways like 2CO and others.
I am in doubt about the best way to start selling subscriptions and ads posting and other features like "featured in homepage", "bold posting" etc....
I mean, i need to understand how to integrate the programming in the websites, with the payments.
One thing i remembered was that i could use the zen cart payment module and adapt it to my sites. Maybe this could be a solution.
If you have any other solution, i would like to ear it.
