I was looking for a simple but robust extension to collect information for membership on my site as well as process payments. This tool worked just perfectly for me. It was so easy to install and configure... I couldn't believe it. I used the PayPal option for payments and everything went smoothly. Due to my own fault, I made a bit of mistake in setting up the form. I submitted a support ticket and Tuan was quick to help and very fast with her responses. I definitely recommend this.... it's worth paying for. Great extension guys!
