Travis mentioned using a "throw away" Skool group for running an auction.
Perfectly good idea.
Here's another...
Create a free group.
Bring people in for the auction.
Make the offer something that solves an immediate problem.
Run the auction and have a blast.
Collect the monies.
THEN...
What's the next problem those bidders have?
Open a paid tier in the group and invite them to stick around and solve that next problem.
I'm setting this up and running it for a few partners as well as my own group.
Even better if a partner has a free group and doesn't know how to monetize it.
Run an auction and invite people to the paid tier.
