A lot of groups that have a good offer, but sometimes there's more questions especially if the membership is not free, it's natural to have questions if this is a good fit before dropping some $ , free trial is a good option, but it smells like a sales pitch, been overused a lot, people loose trust in this method it seems like + there's other cons to it.
Like when you buy on Amazon or Ebay, if you not sure, there's " ask seller a question " button , don't you think it would be a good option before joining skool also ? So anyone can ask a question that they have and that way it can work as an extra sales pitch, in the answer you can send links to other VSL's etc .
