For your next run you should shop around for a different tube supplier, it's a huge portion of your unit cost (24%) and I bet you can drop its price by at least half.
Or consider not using a tube! The bottoms fall out if you shake them to shuffle which has caused at least one case of Zombie Dice ending up in all corners of a small bar to my knowledge :|
I'd consider a bag.
Check out yazoomills.com. They make amazing tubes, and have fantastic customer service. I'm guessing you can get your tube price down to $0.40/tube or less with an order of 2,000 or so tubes.
