Wine price in a retail shop - Italy [closed]

We are planing to go beach-camping to Italy. Since We are trying to save as much money as possible, I would like to know what is the price range for wine in Italy.

Because when We went to France (I am from CZ and France is considered quite expensive), the wine was almost the same price as in CZ (starting from 3 EUR - well, but 3EUR wine > 3EUR CZ wine).

Italy has also its ups in white wine producing therefore I would consider unwise to take the wine from CZ if I can buy it there for almost the same price.

So what is the wine price in a retail shops in Italy? Can You also add some approx. prices for other alcohol?

Edit: I am looking for a decent quality (best price/quality ratio)
