Commonly Asked Questions:

1. Business Model Innovation: Accept the truth of a legitimate business! Our strategy is organising a group buy in which participants share the costs. We use these cash to acquire popular courses from sale pages and make them available to people with limited financial resources. Despite the authors’ worries, our clients love the cost and accessibility we give.
2. The Legal Environment: Yes or No The legality of our activity is ambiguous. While we don’t have specific permission from the course authors to resell the material, there is a technicality at work. The author did not specify any limits on resale when purchasing the course. This legal intricacy is both an opportunity for us and a boon for individuals looking for low-cost access.
3. Quality Control: Uncovering the Truth

Getting to the heart of the issue – quality. Purchasing the course straight from the sale page guarantees that all documents and resources are the same as those obtained through traditional channels.

However, we distinguish ourselves by going beyond personal research and resale. It is crucial to note that we are not the official course providers, which means that the following premium services are not included in our package:

• There are no scheduled coaching calls or sessions with the author.
• Access to the author’s private Facebook group or web portal is not permitted.
• No access to the author’s private membership forum.
• There is no direct email support available from the author or their team.

We operate independently, with the goal of bridging the pricing gap without the extra services provided by official course channels. Your comprehension of our distinct approach is much appreciated.
