Tirana has most things, though ...
Toiletries and Medical Supplies: I would suggest bringing your own razors, since the American razor brands can be extremely expensive and difficult to find.
Miscellaneous: Also bring a good flashlight (torch) as Tirana is plagued with frequent and lengthy power outages.
Luggage and bags: Backpackers are good. But bring some good clothes for the nightlife as well. The locals tend to be a bit fashionable.
Toiletries and Medical Supplies: You can find almost every little thing. There is a lot of import going on with the neighbouring EU countries.
