The $4 individual is for the yearly plan. The monthly plan is $5. If they would give those $2 discount would be quite good and generous like you mentioned but as early adopters I feel that would be a nice incentive and help to justify paying another VPN service. Specially because like you mentioned they should have plans separated since many may not use a lot of things that are in the bundle. Additionally, please consider that in some countries, each added service can represent an outrageous amount to commit to, and those discounts would be greatly appreciated.
