I'm considering purchasing licenses for Events Manager ($75), Shopp ($80 with PayPal addon), and Gravity Forms. Relatively speaking, $199 is a steep price to pay for using Gravity Forms on a single site and only the user registration and PayPal addons.
Carl Hancock's reasoning for making advanced addons available only to Developer licensees was to limit the burden on customer support. However, I'm a developer, so I'm unlikely to add to that burden. I just need a third-party solution for paid user registration to help keep my project's schedule.
Is there any way that I can purchase a single-site license with only the user registration and PayPal addons? If not, does Gravity Forms have the necessary functionality to double as my solution for event management and e-commerce?
