You don't know how the cigarettes have been manufactured, no traceability numbers, it's silly to buy online and never I will do. Let's be serious, tobacco is already bad for health, don't need to add another to make it more toxic.
In the last 15 years, the price went from $3.50 to $7.90 in my country. It's not going to make me buy on the www.
You are right only if cigarettes webshop owners are packing themselves. I find that one of the shops have government excise stamps from Moldova. if it is an authentic image, then it is probably from legal production.
In my country, I buying Sobranie black at $3.50 and there I have the ability to resell.
