You can also review our easy, customer-friendly return policy if you have questions about returns or eligibility.
Do you accept HSA or FSA cards?
Yes! Most mobility equipment, lift chairs, and scooters qualify as eligible expenses under HSA and FSA plans. Simply use your HSA/FSA card at checkout just like a regular debit or credit card.
If you have questions about eligibility for a specific product, give us a call and we'll help you figure it out.
Does insurance or Medicare cover this?
Most online purchases of mobility equipment are not covered by Medicare or private insurance when bought outright. Coverage is typically tied to local in-network rental or DME supplier programs.
Many customers still choose to buy directly because it gives them:
- Full ownership of their equipment from day one
- No rental restrictions or returns
- Freedom to choose exactly the model they want
- HSA/FSA eligible for tax-advantaged savings

Most in-stock items ship within 1 to 3 business days after your order is confirmed. Tracking is sent automatically by email.
Some larger items like lift chairs and power wheelchairs may ship via freight carrier with scheduled delivery. We'll keep you updated every step of the way.
