Fakes -

: If a high-end item is being sold at a fraction of its retail price, it is almost certainly a fake [10, 11, 19].

: Most platforms have protections for buyers, and even if a seller claims "no returns," your legal rights typically still apply if the item is a proven fake [18].

: In Magic: The Gathering, check the printing pattern (rosettes) under magnification. Fake cards often have "jumbled mess" patterns instead of clear, layered ink [9, 26, 43].
