Willow has partnered with Flex to allow you to use your Health Savings Account (HSA) or Flexible Spending Account (FSA). This means you can now use your HSA or FSA debit card to buy select Willow products with pre-tax dollars, resulting in net savings of 30-40%, depending on your tax bracket.

To use your HSA or FSA debit card, add products to your cart as usual. At checkout, select “Flex | Pay with HSA/FSA” as your payment option, enter your HSA or FSA debit card, and complete your checkout as usual. If you don’t see “Flex | Pay with HSA/FSA,” you may be in Shop Pay. Select “checkout as guest” to view more payment options.

If you don’t have your HSA or FSA card handy, still select “Flex | Pay with HSA/FSA” as your payment method. Enter your credit card information and Flex will email you an itemized receipt to submit for reimbursement.

The key here is to make sure you are logged out of ShopPay. One of the easiest ways to do this is to go through checkout in an incognito window.

HSA/FSA cards are debit cards, and the most common reason for declines is insufficient funds. Reach out to your HSA/FSA administrator to confirm your balance.

Please forward us the request from your FSA, and we will work with the Flex team to issue you a new receipt.

Please check your spam folder, as sometimes emails fromnotifications@withflex.commay be automatically filtered as spam by some email service providers. If you still can’t find it, please emailsupport@withflex.comand let them know the email address associated with your order.

No, unfortunately, this isn’t a supported feature right now. If there are insufficient funds in a single HSA or FSA account, you can instead enter a credit card on the Flex checkout page. You will receive an itemized receipt and/or Letter of Medical Necessity from Flex, which you can submit for reimbursement.

Thanks for reaching out, and apologies for the discrepancy. We’ll review the charges and get back to you with details of the likely refund shortly.

Sales tax for eligible items is also covered by HSA/FSA funds. If the customer has a split cart, the tax will be divided among the cards based on the items.
