User Experience
The $70 is divided between the group. There are 40 people in her group (including Stephanie) which means that everyone pitches in $1.75. Because Stephanie is also a group member, she pitches in $1.75 as well.
Stephanie ends up paying $1.75 for what would normally be a $70 expense (a 97.50% savings)!
