You have to bear in mind that a lot of us in Australia (myself included) have watched rhizomes in July and August fetching prices on ebay.com.au for $112 (yes stupid - I know) for a single cascade rhizome. The majority have refused to support this nonsense.
I myself have bought rhizomes from one of our sponsors Gryphon Brewing for a sensible price ($25 each) when they were available there, but have also been hanging on until the end of the planting season (which is now for us down in the southern hemisphere) to see if any go begging on ebay at non-inflated prices. Thankfully that time has come as ebay hoppers realise that demand for their stuff will soon dry up (pardon the pun) as our weather hots up.
I am glad the prices are not that high here. We have enough problems with the druggies steeling any kind of metal for scrap. I could just see them pulling the copper wire from the irrigation pumps, the aluminum irrigation pipe, then digging up half the field and selling the rhizomes on ebay (the worlds biggest fence).
