The kanji 購 is a phono-semantic compound (形声文字). The left side is the radical 貝（かい）, which represents "shell" or, by extension, "money" or "wealth." The right side is 冓（こう）, which acts phonetically and originally meant "to meet" or "to build." Together, they combine to form the idea of exchanging something (money) to obtain something (goods/services), hence the meaning of "to buy" or "to purchase." The character visually represents the idea of a transaction, where money changes hands to acquire an item.
