Try the link below. I actually bought mine from the U.S. on a going out of bussiness sale but $40 a pound Canadian is the going price.
Also check your municipal waste program some carry them or have links to people in your area.
Another option is to go through your composter and pick out the smaller red worms. The redworms in my back yard are slightly smaller than the Eisenia Fetidas but will work. Dont bother with the super long and fat ones they wont survive and don't eat enough.
Keep us posted on your progress and feel free to email me directly if you want some help.

Thanks Maria..that was a quick answer! I also remembered a newspaper article I had clipped out on a new store just opened in London called My Green Garden. I just looked up her website and she has worms! $22 for 1/2 lb. She has lots of other neat stuff too for gardening organically-organic fertilizers, compost teas and castings and pest controls etc.
I just emptied my compost bin into the veggie garden and moved it last week, so that won't be an option!
About 8 years ago I stayed in a youth hostel in Brunswick, Georgia...it was a real 'hippie' kind of place in the woods, with geodesic dome house, treehouses and composting toilets. Anyway, they had a large wooden trunk in the common room as a coffee table and no one would have ever guessed that it was also their worm bin! That was where I first saw a live worm bin and I've thought about having one ever since.

Thanks for the informative website and links, boreal wormer.

Hi wyndyacre! I got mine from Cathy's Crawly Composters Anisten posted the link to her site. Sounds like your London store may be your best bet though...my 1/2lb was 36$ after shipping costs.

Happy worming!
