Yes I have seen them in store
Not in-store but online. There is a medical supply store in Houston.
Cynthia Martinez I would call the pharmacy and ask. I do believe that I've seen one but maybe you should call the pharmacy.
They don't have at the store, you need to order online
In stock $150.00 according to web site. I've never looked to see if they are physically there. I would check the internet for medical supply stores that sell publicly. Health insurance and Medicare and Medicaid pay for them usually. They can be rented also from some pharmacies from my experience. Rented one for my mom before she passed away 3 years ago.
