Beth, I don't know where you are, but if you have one near you Costco
(warehouse store) sells them by the box (the latex ones, haven't
looked for the nitrile ones). I use them for a lot of things around
the house, so I keep them in but don't want to store cases of them.
The other option would be to ask a local doctor, vet, or dentist
whether you could buy a box or two from them.
