Please remember that the transfer of these, and similar items, for in-game gold (virtual currency) is not supported. While our In-Game Support staff may be able to investigate these matters and take appropriate actions towards the scamming account, we are likely unable to assist with the reclamation of any virtual currency exchanged for the product.
As mentioned above, and to expand further, this applies to all such transactions that fall into this category including: purchased virtual pets and mounts, game time cards, and Recruit a Friend and Scroll of Resurrection promotional benefits.
Ownership/Selling of the Account or Virtual Items.
...Blizzard does not recognize any purported transfers of virtual property executed outside of the Game, or the purported sale, gift or trade in the “real world” of anything that appears or originates in the Game. Accordingly, you may not sell in-game items or currency for “real” money, or exchange those items or currency for value outside of the Game.
For further clarification, any virtual items that can be placed on the Auction House for sale, such as the majority of TCG pets/mounts or other in-game non-combat pets, which are Bind on Equip/Use, may be purchased for gold.
Cosmetic Helms: With the addition of these cosmetic items we thought it important to add a section on them.
While the helms themselves are considered virtual, they cannot be traded in-game and as such, should not be purchased for gold. Attempting to do so can have negative repercussions the least of which could be that the other person is scamming you and you will lose whatever gold you traded as well as the helm.
