I would personally suggest using WarriorPlus over using JvZoo
But to each their own, and Both Warriorplus and JvZoo ipn files are included and work for subscriptions and 1 time purchases as well as selling bundles.
As for paypal smart buttons, if you do go that route let me know and I will have you drop 1 line of php code into a php file for you to set as the web hook url to that file, and do a test purchase so I can see the variables sent to the file and be able to build it out for you if it differs from the normal paypal variables sent.
Thanks man. Im not going to sell bundles. Do you think Its better to use just the paypal buttons? Or warrior+ have more to offer?
