Ben, at the hospital we call it "making the best possible use of the available resources", not scrounging. <img src="/images/graemlins/grin.gif" alt="" />


As for getting low cost supplies:
Any supplies in a patients room are thrown away when discharged, so I have added some supplies to my FAK this way.
We try to save the stuff not used for medical mission trips or education if possible.
Harbor Freight and Northern Tools have tables/bins full of inexpensive chinese tools lining the aisles of the store, have found some good deals there.
Yard sales, though tools can be wildly overpriced.
Dollar stores, of course.
Big Lots, if there is one near you.
