Hi kokarat, Probably Drupal as it has a variety of ecommerce plugins that can be integrated with PayPal quite easily. I find that Drupal is easier to use than Joomla so I would say Drupal. You could also consider using Wordpress as Wordpress also has great ecommerce features and although it is not generally considered as a CMS it is even easier to use than Drupal or Joomla and has a level of user control. Take time to decide because once you decide which CMS to use you will have a big learning curve to navigate and switching from one CMS to another is often like starting all over. Good Luck and enjoy.
I recently built an e-commerce site with Magento, I really like it. Also there is a free version which is very feature rich.
Hey Kokarat , I'd say getonic.com is the way to go. It's a kind of online marketplace for digital goods, and you can pretty much sell anything you want (as long as it's digital, of course!). I found it very user-friendly, plus it's free . Best of luck!
Personally, I would opt for Wordpress. The platform is very easy and lots of tools/plug-ins can be used there for free. Drupal and Joomla can be very complicated.
I think you should go with Joomla. There is a large joomla community out there where you can find the suitable theme and plugin for selling digital goods via your site.
