RE: Drohn's Pokémon Centre - Pickup Service from Japan's Pokémon Centre in Fukuoka - Plushes, Cards, and much more!
Emphasis mine. What was included in the promo packs was a poster, not a playmat.
Drohn said:They didn't have them last time I checked, but I'm picking up multiple for DarkPkmnTrainer if they stock/restock them. I'm not sure if they already were stocked or that they still have to be stocked. I haven't seen them myself. I do know they were included in the Charizard promo packs, but I haven't seen them separately. They don't have the promo packs anymore at the Pokémon Centre but did have some at Toys R Us last time I went. They might still have them there.
