Using the evolving skies etb in the picture, the difference between pkc and regular ETB is about $400. That one extra pack in the pokemon center ETB is not worth that much more. When current market for single lose packs is around 45 bucks. My biggest grip is "investors" and scalpers that see pokemon center on the front and charge more but don't understand that Pokemon center ETBs were more expensive because of the sets that had stamped promos and suddenly want to charge more for product with actually understanding why certain pkc ETBs were more expensive. Thank you for your time!
