Some businesses cover the cost of Pay By Group for their customers, thereby making it free for you to use! If they do not, Pay By Group charges a fee of $2.50 to each customer that participates in a group. Some businesses that use Pay By Group have different fee structures than this one, however.
Pay By Group will always display the specific fee structure for any given purchase in multiple locations. Organizers will first see the fee structure for their group on the right side of the claim form when they create their purchase:
If you have yet to sign up for a share of a purchase, the fee structure can be seen by hovering your mouse over the ? icon next to Your share on the right side of the purchase dashboard:
Finally, the fee structure can be viewed by clicking the Details link on the right side of the commit form when you sign up for a share of the purchase by clicking the Contribute button:
If there’s no mention of a fee, then the business is covering it for you and you'll only be charged the exact share amount you commit to (or less, depending on how many other people join the group).
