I'm not sure, but I'll offer a couple of guesses:
1. Low demand. None of the garden centers I have visited have even heard of Comfrey.
2. Of those online places that do know of Comfrey, many offer a specific cultivar. That requires splitting Comfrey for propagation, and so the costs go up.
In the end, the seeds aren't that hard to collect. I've got some in the basement myself from the Comfrey I planted last year from seeds I got from Horizon Herbs.
