The simplest and easiest is to go find someone whom works in the medical field, ie. nurse, or ems personel. and just ask them. Trust me...............you could do that and be restocked on the spot for free.
And thinking of it..............i'd say if you walked in to any EMS station. stated your need and brouight your kit with you, i'd bet they'd probably help you out no questions asked. Lastly if you run out of options, just ask one of us, your fellow ETS'rs and we'd be glad to help.
