Given the fact that Medulin is a rather small city, which is also very close to Pula (the capital of Istria), the shopping opportunities are of course rather limited. They limit themselves to a few supermarkets (Plodine, Konzum, Lidl) where things can be bought for daily use.
Then there are some souvenir shops, a hairdresser, a wine shop and several smaller kiosks.
In neighboring Pula you will find more shops in the City Malklsuch as Kaufland, dm, Müller, New Yorker, Deichmann ...
