I paid $12 for 1/2 pound, but if you want free you will need to find a location that doesn't use traditional fertilizers. Most lawn and garden fertilizers are salt based and kill worms and it takes a year or 2 for them to come back. You can try the bait shops as well, if they have some that are near death they may be willing to sell them cheap.

I'll also put the link I used to start my worm bin, which is very easy.

Worms for vermicomposting can be ordered but are much easier and cheaper to get at your local bait shop. Regular earthworms don't cut the bill quite as well as the red wigglers or to get technical. Eisenia fetida and Lumbricus rubellus are both used successfully in vermicomposting. But the easiest way is to go to the bait shop and ask for red wigglers/redworms.
