Over the last couple of months would have been great.
occasionally you see some give aways on here but usually it's around $10 plus shipping from blokes on here.
If you are keen to get some growing this season I would bite the bullet and quickly buy some off ebay and pot them up, you won't get great results but you will then have them and next year they should go off.
Or ask around to see if anyone local to you would be willing to allow you to take a cutting.
