I am reviewing the 23 Piazza Gaetano Salvemini location(less than 10 blocks east of the Duomo). They accept credit cards if you buy more than 10 items. They have the most amazing uniquely European goods in addition to the useful but junky made in China stuff you find in the US99 cent stores, such as: Italian make-up, Austrian chocolates and marzipan, European boxed juices and pastries, and Italian greeting cards. It was such a fortuitous find for me. Now I can skip the Heidemann store at the German airport and enjoy my 1 Euro bag of Austrian marzipan and save a ton of money, too!
