I looked in the phone book and found a medical supply place that was about 4 blocks away. Went in a couple of weeks ago, and found that they sold the larger quantities in bags of 25, 50, 100 + and when I told the lady there that I was only looking for two for use with ecigarettes, she pulled out two of a bag that had been ripped in shipping and a couple broken that they were returning to the manufacturer. They were glass and had permanent markings on the outside. She sold me a couple for $10 because since they couldn't be sold (glass fragments in the package) for their intended use. These are normally like $15.00 + a piece. You might check locally and see what you can find in glass.
