There were 3 that came up when I searched;
although the prices sound great, 2 of the auctions involve $20 shipping fees on top of the price of the rhizomes!

Did you check the shipping options? There should be a flat rate box for about $14.50

I've had the best luck getting rhyzomes from the ebay seller, dip-r-den. she has the biggest iris & the best selection of any of the sellers. I've got 4 more coming from her right now. she also has kasperek iris up for bids right now. check it out, she has a lot of iris up for bids right now. some really pretty ones are available.

I just got my last box of iris from dip-r-den last week. it was supposed to be 14 but she sent 27 in the box. 13 extras! what a deal. they are all planted already. they were bigger than the ones I already had here. I can't wait till next spring to see all the new iris bloom. but, I know 2012 will be even better.
