Use your FSA + HSA dollars at Kinship.
The easiest way is to simply purchase eligible items using your FSA or HSA card at checkout. Alternatively, you can use your own credit card at checkout and then submit a receipt to your benefits provider for reimbursement.
While HSA dollars roll over each year, FSA dollars that you elect to set aside typically expire on 12/31 each year. Double check with your benefits provide and don't forget to use your benefits before they expire.
