Hello Katrina,
Have you tried the 1/2 gallon or 1/4 gallon plastic milk jugs? They are inexpensive and you might even be able to collect them from families and friends, store easily in a crate and should hold longer than 1 season. It is plastic, which I personally try to avoid, but if you can reuse empty ones and get some more life out of them that would be good. Hope that helps:)
