Can you purchase a Groupon with an FSA?

Provided that the Groupon item is one that is FSA eligible, yes. Keep in mind that FSA cards are restricted to only approve at appropriate merchants, so since Groupon is not a typical merchant where FSA items would be sold, you may need to submit a claim manually for reimbursement vs. using your card.
