If you need an "all-in-one" solution — affiliate programs, billing, and so on, meaning if you are in the info business, have referral systems, and multiple payment options, this service will be an excellent choice. Overall, everything is top-notch, except for the inflated price, which is unclear in its justification and does not allow you to choose only the necessary modules. Unfortunately, even the most minimal package I needed cost me $95 a month. With a small subscriber base or low-priced info products, this is not feasible. However, this does not diminish the overall value of the service.
