Shops in the dormitories

In Tx dormitories, there are something that will surprise to everybody, even people who are living in Wroclaw, and isnt known for a lot of people. Is that in Tx dormitories, some Poles have a kind of shop in their rooms! While you´re cooking, or in the bathroom you can see a little stickers on the walls, where you can read beer brands, prices and a room number, and it is because some Poles are dedicated to go buy beer (to somewhere where they get it cheaper than in supermarkets), and;resale; in the dormitories, and they offer good prices, not higher than in supermarkets, even in some cases are lower! Some lazy people prefer to go to this kind of shops, than go to the supermarket and carry liters of beer, and the next day go again. But is not only avariable beer, vodka too, homemade vodka (distilled by themselves), and they also sells food products! products for washing machine (laundry detergent and fabric softener). In Tx is where you can buy everything you want, including illegal products... haha!
