What’s an HSA or FSA?

Both let you set aside pre-tax money for qualified health expenses. An HSA is a personal account you keep; an FSA is run through your employer and typically has to be used within the plan year.

Is every Polsen watch HSA/FSA eligible?

Yes!

What if my card is declined?

Try a different HSA/FSA card, or split the payment with another card. If it still doesn’t work, your plan administrator can confirm what your plan covers.

Can I split payment?

Yes, use your HSA/FSA card for part of the order and another card for the rest, all in one checkout.

What happens if I send something back?

Returns are refunded to the original payment method(s), in the same proportions you used to pay.
