Neth says they've covered this issue before in the forums, but I don't remember ever covering it here: Why can't you sell enchants on the Auction House? All of the "production" professions allow you to post your wares in the AH so they can sell even when you're offline, but not so with enchanting-- to make some cash, you've got to stand in a city and spam away until someone comes along who wants your enchant.

Lots of players have said that it would be nice if enchants could be stored on scrolls that could then be sold on the AH, but Blizzard has said no-- not only is Enchanting an "elite" profession (mostly because it's the only* a "production" profession that doesn't have an associated gathering one), but Blizz wants us to make like we're nice or something and actually coordinate in-person enchanting.

Of course, there's a whole new twist to this issue now-- quite a few factions in Outland sell special items that will grant enchants, and leatherworkers can even make special enchanted armor kits that can be sold on the AH. And yet enchanters are left completely out of the moneymaking loop. Given these new developments, I'd imagine that no matter what Neth says, Blizzard should think very seriously about allowing enchanting scrolls. Not only would they be giving enchanters a larger market to work with, but consumers would benefit from lower enchanting prices. Enchanters who make tons now would make less per enchant, but so many more chants would be sold that everyone would benefit.

Update: Tailoring is also a production profession that doesn't have a gathering one associated with it. *Head smack*-- thanks olhado.
