I just signed up and am kind of regretting it. The enrollment fee is $10, according to the fee schedule.
There is a $2 inactivity fee (90 days). Of course, I have no idea how long it would take me to earn enough money to keep a card like that active. I wish there was a way to add money to it outside of Jingit.
What is the earning potential here? How much do you get for a check-in?
