@Grivusangel -- I'm sure the expense comes in part from transportation costs. The honey is usually imported from New Zealand, so that explains the price, at least in part.
As I understand it, the only place the manuka plant grows is in New Zealand, so manuka honey is only made in one place, which also contributes to the cost.
I don't know if regular honey would help with wound care or not. You might ask the proprietor of the health food store. He or she might know. A doctor who is open to alternative medicine might also know whether any kind of honey is good for wounds.
