Sorry, but I am not quite sure what you mean.

If I need something, I look into a catalogue, get approval for funding and order it.
There is not much equipment that I need for my patients and what I need is readily available.

The only issue would be the cost, i.e. patients not being able to pay for equipment that no insurer funds and that you cannot buy in a $2 shop.

What is your problem?
Is noone ordering from your supply?
Who are you working for?

Cheers,
Fyzzio
