Look for a Juice distributor/packager. We have a Seneca plant in town that sells them for +/- $20 each. A lot of places that go from bulk foods (in the blue plastic 55G) to retail packaging, just sell them instead of tossing them. I can check the prices if your interested. My guess is you can find someone producing them much closer to you.
No promises, but if you get hung up, I could probably facilitate getting you a set. I might even be able to deliver (for a nominal fee), my dad still lives in Rent'n and I do pop over from time to time.
