Guys, consider that she's 19 and won't have 3000-4000zl a month to play around with.
She'll be sharing a flat - so more realistic is 400-500PLN.
Very ordinary white bread 2PLN to 2.50PLN, yes, not too difficult to find at that price.
Easily found at that price :)
but more generally milk is around the 2.5 to 3PLN mark. The better filtered milk 3.5PLN for a litre.
Normal, bog standard milk in a supermarket (without any marketing gimmicks) is about 2PLN.
Produce is cheapest in season of course. Apples are around 4 to 5PLN a kilo right now. In the next month or so they will probably be 3PLN a kilo.
Indeed. The price of cherries right now is just flabbergasting - I saw exactly the same thing in Germany for 5 euro/kilo!
