Tobacco prices in Greece are controlled, and are the same everywhere. Maria's paper shop has a wide range, and she'll order it for you if she doesn't have it. Deliveries are on Thursday, so you need to order by Wednesday. I usually order fags before I go, which is usually Friday, so that I can pick them up on Saturday - that's because I always buy Greek cigs - they're fine and cheaper, and it supports the Greek economy. I don't know about Greek rolling tobacco, but Maria, who knoweth everything, will advise if you want to give it a try.
