I just tried to place an order for 500 night crawlers from DMF Bait Co. They couldn't fill the order at this time They said it was a had winter in Canada for the worms and the spring was also bad. They hope to have the problem resolved in the next week or so. It's the "or so" I'm concerned about. I may have to buy some worms from Walmart.
I also have a bait shop I do emergency business with. They have plenty of worm but are almost twice the price.
