Just to follow up, I was at Costco today. They sell 2 packs of gloves, 300 prs. total for $14.99. For that price, it's hardly worth buying them in smaller quantities. As someone else wrote, if you have to actually use them in a first aid/emergency event, you're most likely gonna use a couple pair minimum. 
I keep 3 pairs in my belt pouch, another 3 or 4 pairs in my "jump" bag, and a couple more in my O2/airway bag and a spare box or two in my vehicle. Cheap insurance in my case.
