I was referring more to collections not released there, which is this case... With this new Panini approach, you can get at home, in just 1/2 days, something you can't get in stores... However, for people who would like to buy sealed boxes and/or more than one or two, it's still better some online sellers.
But yes, I know that store and like I said many times, I just wished we had something similar here.
For sure they're not buying blisters (unless sellers like them also sells blisters)... And I'm almost certain they also don't buy "directly" from Panini Russia... There's always someone, somewhere, who has access to those stickers (either from Panini or with some strong connection) and in times like these, like you wrote, it's better to keep the sources private... Like we say here, it's "business done by the horse's door".I did not ask him directly as most collectors and traders prefer to keep their sources private.
But honestly i cannot imagine that any sellers of these sets buy 100 blisters upwards to receive maybe 4 complete sets.
The sellers i know have more than just 4 sets that´s why i believe that they are ordering the Russian extra stickers directly from Panini Russia.
