Short Answer: FSA stands for Flexible Spending Account and HSA is Health Savings Account.
More Info: A flexible spending account (FSA) or health savings account (HSA) allows consumers to deduct pre-tax dollars from their paychecks and then deposit them into an employer-sponsored account. The funds in that account can then be used to pay for approved health-related expenses–including many over-the-counter medicines and health related items that can be found for sale at OverstockDrugstore.com.
Approved items are indicated on our site with the FSA Checkbox . Or you can choose to filter your shopping results to only show FSA/HSA eligible items.
