I once had a comb with the honey in it, it's much better than normal honey, but there is a lot of honey in a small amount of comb.
If you are interested, they now sell frames that have the comb containers built right in... all you have to do is remove the filled comb and put a lid on it, then put an empty container in the frame and replace the frame. It tends to be more expensive to start, but it saves an awful lot of work in the long run and since it is pre-packaged, all you need to do is label it and sell it.
As an added note, the comb is usually formed by the ingestion of honey and it generally requires approximately 8 pounds of honey to create a pound of wax. That is one reason a lot of beekeepers do not sell comb honey is becau8se it ir requires a loss of honey.
