I feel something weird about this Shop

Hello my Pokébros,

I found this lovely shop in Livigno Italy and I love to collect Pokémon cards, I am here because of the winter Olympics but like I wrote in the caption, something is strange in this Shop. My knowledge is not the best at Pokémon tcg because I started in December 2025 with my collection so actually I am a noob 😀

They look very original and not resealed.

I bought about 5 japanese packs and pulled one AR the others werent special.

Thats why I need some of you experts.

My first question is why are some prices for the same booster packs are different?

1. Why are some just 3-4€ and some 12-15€?

2. Are these even original and really not resealed?

I hope some of you can help me out…if you need more detailed pictures from the package or anything to identify if those are original.
