     BACKGROUND 
     1. Field 
     One or more embodiments relate to a collection bundle purchase device and a collection bundle purchase method. 
     2. Description of the Related Art 
     An online game is a computer game that is implemented so that the computer game may operate on a wired or wireless network, and an online game player may play a game with another person in a remote place through a wired or wireless network. 
     A role-playing game is a computer game in which a game user assumes the role of a character appearing in a game program and performs the role directly. Role-playing game players travel through the world of adventure and imagination according to rules set by a game manager and perform various missions, so they may feel as if they are the main characters in the game. 
     In particular, Massively Multi-player Online Role Playing Games (MMORPG) that allow multiple users to simultaneously participate and perform various missions (quests) on a game map implemented in a virtual space are gaining popularity. 
     Items are things that game players&#39; avatars acquire, which may be manipulated and require a storage space (inventory). In fantasy novels, the items are often used as an abbreviation for magic items. Strictly speaking, an item may be viewed as a trigger to access a specific program in the game.

     As used herein, a phrase referring to “at least one of” a list of items refers to any combination of these items, including single members. As an example, “at least one of a, b, or c:” is intended to include any combination with multiples of the same element (e.g., a-a, a-a-a, a-a-b, a-a-c, a-b-b, a-c-c, b-b, b-b-b, b-b-c, c-c, and c-c-c, or any other ordering of a, b, and c), as well as a, b, c, a-b, a-c, b-c, and a-b-c. 
     As used herein, the term “determining” encompasses a wide variety of actions. For example, the term “determining” may include computing, processing, deriving, examining, looking up (e.g., looking up in a table, database, or other data structure), identifying, and the like. The term “determining” may also include receiving (e.g., receiving information), accessing (accessing data in a memory), and the like. The term “determining” may also include resolving, selecting, choosing, establishing, and the like. 
     The description herein is for describing the disclosure and numerous modifications and adaptations will be readily apparent to one of ordinary skill in the art without departing from the spirit and scope of the disclosure. 
     In this regard, the present embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein.
