You can get a large quantity of these on for cheap, especially if you'll settle for off-brands or here is a major brand that's not terribly old stock, $3 for 5:
digikey.com has far better prices for coin cell batteries. And they have bulk discounts, if you're into that. - Technician
They do if you're placing an order there anyway, but if just getting batteries, best guess is you'd have to get more than a dozen to come out ahead after the shipping charge, and maybe a lot more than that if they're shipping Fedex like some I saw.
