In the Yu-Gi-Oh card game, values vary with card rarity. some cards are reprinted as higher or lower rarities, which cause price fluctuations. typically a 'meta' deck will cost around $1,200 USD because of the shear demand of the cards it contains. there are some occasions where this value is less or greater: in the 'teleDAD' format, the meta deck costed about $3,500, however after 2011's national tournament, the most used meta deck cost only about $500.
Most yugioh structure decks cost around $12 in a store, though they usually only have the newest ones; each deck varies in cost from about $8-$15. I recommend going to www.gamingetcstore.com to get anything yugioh card related, because their prices are reasonable.
