If you are talking about hemostats and the like I ended up getting mine at a gun show of all places. Hubby is a certified range instructor and his passion is shooting sports. Turns out they use all that medical type equipment for working with those tiny screws and cleaning the equipment. They had everything from german made hemostats and sissors in all sizes, scapal blades, hospital tubing, skin staple gun, etc. Now I don't mind going with him as much! LOL!!!
It depends on what kind of supplies you are asking about? As for the list of what I have to whelp a litter it is betadine, hemostat, unflavored dental floss, scissors, bulb syringe, ky jelly, thermometor, and lots of towels and newspapers, and a scale to weigh the pups and some karo syrup for those slow to start pups that's about all I use to whelp a litter besides the whelping box.
