How to make a group buy seo tools website

[Nameuniecto]

Hi everyone, hope you all are doing great.


I am just curious to know how to make a group buy seo tools website. Not going to take any name but what they do is they provide many seo tools for a cheap price like 30$ or something.

I want to know how they do it.

Thank you

EDIT: toolspur[dot]com check out this service. I want to make one like this.

Could you be a little clearer? I don't exactly understand your question.

Not sure others would easily understand this either.
