Remembering how the last Yugioh box collection sold out practically immediately once it hit shelves, I decided to order mine online. It saved me time and hassle from looking for them in stores.
Now as for the product, it's fabulous. Within the box comes a play-mat, six cards containing new artworks of older cards that the protagonists used, and six booster packs of five cards that vary between brand new cards to old cards that are powerful or in demand (as far as I believe). There are at least 100 different cards you can get.
Some example of cards include the Ghost Girls, the Hot Red Dragon Archfiends, supports for the Dark Magician series, and many more. Even if you only get one of the boxes of Duel Power, you get at least 36 cards that either boost your deck, add to your collection of cards, or even have good cards to trade with your friends. A must buy for those who love the card game.
