The standard 151 Elite Trainer Box is described with nine 151 booster packs, a Snorlax promo and gameplay accessories. The separately named Pokémon Center edition has a different configuration.
Compare the exact edition
For an edition comparison, the original announcement lists 11 packs and two Snorlax promos for the Pokémon Center edition, rather than nine packs and one promo for this standard box.
Plan the checklist before opening packs
A particular card or printing is not guaranteed in random booster packs. Fixed promotional items listed for the factory product are separate from random pack contents. Check the expansion, language and edition before adding an item to your collection.
