Q: How do you ship?

We ship our packages via UPS

Q: When will my order ship?

Most orders placed by 2pm CST Mon-Fri will ship the same day.

Q: How long will Ground Shipping take to get to me?

Shipping times depend on what state you are shipping to. We ship from Houston, TX and San Francisco, CA, so we are usually 3 days out from anywhere in the continental US.

Q: Will you ship internationally?

At this time, we only ship to the continental US, Alaska, and Hawaii, and Canada with an approved order. Additional shipping charges will be imposed for shipments going to Alaska, Hawaii, and Canada. Please contact us for an estimate.

Q: Can I choose a faster delivery method than Ground?

Yes, you may also choose 3-Day, 2-Day Air, or Next Day Air. This will ship via UPS or FedEx, depending on the warehouse it leaves from. Order must be in by 12:00PM CST for expedited processing. Some products only the manufacturer is capable of programming, so they need time for this as well as time to ship.



Q: Do you accept purchase orders (P.O.)?

There are several hospital and eldercare facilities that purchase from us on a routine basis in which we use purchase orders with. If you are a routine customer and think you should have the same privilege, let us know!
If you just need an invoice to for payment we can provide that for you before shipping as well.

No. Payment is required in advance for all purchases. We accept all major credit cards. We also accept personal checks or money orders drawn on US banks.

Q: Will you bill Medicare / my insurance company?

Unfortunately, we cannot submit bills to Medicare or insurance companies.
