Our store 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 our 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 log in to the consumer portal at app.withflex.com using the same email you used at checkout to download an itemized receipt to submit for reimbursement.

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'll work with the Flex team to issue you a new receipt.

Please log in to the consumer portal at app.withflex.com using the same email you used at checkout to download all the documents needed for the product you purchased. If you still need help, please email support@withflex.com and let them know the email address associated with your order.

No, 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 can then log in to the consumer portal at app.withflex.com using the same email you used at checkout to download an itemized receipt and/or Letter of Medical Necessity, which you can submit for reimbursement.

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 you have a split cart, the tax will be divided among the cards based on the items.

Some products require documentation from a licensed healthcare provider stating that the item is necessary to treat or manage a specific medical condition. If the product requires a Letter of Medical Necessity (LMN), Flex facilitates a chat-based telehealth consultation reviewed by a licensed provider, and typically the Letter is provided within 2 hours.

To qualify to use your HSA or FSA card for our products, the IRS requires you to have a Letter of Medical Necessity. Our store has partnered with Flex to enable telehealth visits as part of checkout. A licensed provider will review your consultation, and within 2 hours of your purchase, you can log in to the consumer portal at app.withflex.com using the same email you used at checkout to download your Letter of Medical Necessity and itemized receipt.

Keep it on file for at least three years in the event of an IRS audit of your HSA or FSA account. Occasionally, FSAs may ask for the Letter to confirm the eligibility of your purchase.

Please email support@withflex.com and they'll reach out to their telehealth team to reprocess and send your corrected Letter of Medical Necessity.

This may be a time zone issue. We'll reach out to our partners at Flex to see if they can reissue the Letter with an updated date.

Generally, we're not able to accommodate one-off requests, but we'll reach out to our partners at Flex and see if we can accommodate your request.

We strongly recommend checking with your HSA/FSA provider to see if a purchase is eligible prior to completing the purchase. If you believe your claim has been wrongly denied, please send over any response from your HSA/FSA provider to us so we can share it with Flex and receive guidance on the next best steps. Note that employer-sponsored FSAs can determine what products are eligible beyond the IRS's guidelines, so it's important to check prior to purchase.

The ability to apply for FSA reimbursement in a future calendar year depends on the policy of the specific FSA provider. Most FSA administrators require that the purchase be made during the time of coverage. For example, if the FSA coverage is for 2025, all purchases typically need to be made and/or submitted for reimbursement within that coverage period. However, some administrators may have more flexible rules. We recommend reviewing your plan policy to confirm the details.

Note: Health Savings Accounts (HSAs) are different and generally allow for reimbursement at any time, even in future years.

For purchases made without using Flex at checkout to receive an itemized receipt, it may be difficult to apply for reimbursement. For Health Savings Accounts (HSAs), you can use an itemized receipt for reimbursement anytime after you've made the purchase, even years later. For Flexible Spending Accounts (FSAs), most accounts require the purchase be made in the calendar year during which you had the FSA, as FSAs typically do not roll over. Some FSAs offer a buffer window allowing additional time to submit receipts for expenses incurred during the previous year.

1. Complete your health consultation. Complete a brief, 2-minute consultation. A licensed provider will review your responses and determine your eligibility. If eligible, you'll receive a Letter of Medical Necessity within two hours.

2. Make your purchase. Pay for your order with a standard payment method. Do not use your HSA/FSA card at checkout.

3. Submit for HSA/FSA reimbursement. Follow Flex's instructions to submit your Letter and itemized receipt to your HSA/FSA administrator for reimbursement.

1. Locate your HSA/FSA administrator (typically through your employer's HR department or health insurance provider).

2. Log in to your account on the administrator's online platform.

3. Navigate to the "Reimbursement" or "Claims" section.

4. Upload your Letter of Medical Necessity and receipts for related purchases made after the letter's issue date.

5. Submit your claim. Processing can take several days to a few weeks.

Reimbursement times vary but can take several weeks. For a specific timeline, contact your HSA or FSA administrator directly.

Certain states — Louisiana, New Mexico, and Mississippi — have local and state laws limiting telehealth services. Flex is unable to provide Telehealth Consultations and Letters of Medical Necessity to customers in these states.
