That's where I got them from, Specialty Bottle. They are reasonably cheap from many places but it was hard to get the shipping down. Specialty Bottle had the best price on shipping. I think all you see turned out to be $1.92 per container including shipping. Above all, they really look cool. They also have clear and amber ones. I just prefer the blue.
I went with the colored ones to help prevent sun degradation. Figured I would point that out. Not sure if Amber or blue is better for that but hopefully it helps a little. Of course it is just easier to store them out of the sunlight.
