Buying WIND SIM in Milan

[bigdoofus]

Greetings. I will be taking a vacation in Italy soon and the website has been very informative in deciding which prepaid SIM to choose. Since I want to use data, it looks like WIND is the best deal. I will be landing in MXP and then going to Milano Centrale. Is there a WIND reseller at either MXP or Milano Centrale? I will be taking another train to Venice shortly after arriving at Milano Centrale so I won't have that much time to wander around Milan looking for a store. I am aware of the codice fiscale issue. Will a WIND branded store care if it was generated online?

Thank You or Grazie to the Italians
