Just posted, BestBuy.com has Prismatic Evolutions blister packs available for pre order!
You can find the Prismatic Evolutions blister packs here: https://www.bestbuy.com/site/pokemon-trading-card-game-scarlet-violet-prismatic-evolutions-2-pack-blister/6607716.p?skuId=6607716
These blister packs are going to prove pretty popular! Interestingly PokemonCenter.com released two Surging Sparks blister packs at the same time the PE blister packs became available. We’ll see how long both stay up for sale. I imagine not long since both have a lot of hype around them.
Which is exactly why you should order as soon as possible! Product at MSRP is going to become harder and harder to find and you don’t want to end up paying a ton of money to scalpers or hoarders.
