We source our Pokémon cards from sealed booster boxes, sealed booster cases, and high-integrity suppliers who don't weigh packs and source their inventory the same disciplined way we do. That standard exists for one reason: the chase cards in a set carry a foil layer that makes a hit-bearing pack slightly heavier, and anyone with a cheap jewelry scale can sort a batch and skim the winners out before the rest ever reaches a shelf. Buying from sealed cases and like-minded suppliers is the only way to guarantee the packs in our machines still carry their full, published pull odds — untouched, unsorted, and unsearched.
Loose booster packs are risky to buy, and they are often cheaper than sealed product for exactly that reason. A discounted loose pack is frequently the light leftover after a batch was weighed and the hits removed — or a resealed pack with the winner already pulled and a common dropped back in. The low price isn't a bargain; it's a signal that the value is already gone.
We would rather pay more for sealed, honest inventory than pass searched-through packs to customers, because vending runs on winners: real pulls are what build the hype and repeat play that keep a machine profitable.
