Builders Club Only items are those which can only be purchased by users with a
Builders Club membership.
Limited Items are those which were once sold by Roblox and will not be sold again. Users who own these items can re-sell them to other users for the price of their choice.
Limited Unique Items are sold by Roblox until they run out (we could release, say, 100 of a certain hat.) When you buy these, they are stamped with a serial number (i.e. 7 / 100) that shows which one you got.
Once these items run out, they can also be sold to other users.
