I'm new to WordPress and don't have a lot of development experience. I had a little trouble with the installation and contacted Niaz. He responded in less than 24 hours and was very helpful. We exchanged a few e-mails and finally realized it was my error in the installation.
The plugin works perfectly. In retrospect it was simple to setup, I was making it more difficult. It works great with Paypal and e-mail notifications. Order processing is a breeze. It's simple - I like simple. I'm very pleased.
