All team stores have a fundraising option! It can be found in your admin dashboard.
Once selected, choose "Enable".
Then choose the % you would like added to the items on the team store.
If you choose the 10% option all items would be marked up 10% on the store. So a $20 item would show as $22 on the team store.
Fundraising checks are mailed out at the end of the following month after the orders have shipped. So, if the orders ship mid January, the check is then mailed out at the end of February.
