I have had dealings with with the Inter Store and they have been nothing but professional. When I was in Milan last season for our first home match of the season, I was unable to buy any shirt (home or away) with the Scudetto patch. They had sold out and I had to return to Australia empty handed. I ordered a few months later and everything went well.
I ordered our Centenary home and away shirts a short time before Christmas and they arrived about three weeks ago. The shirts are beautiful and I have no complaints to make about Inter Store.
With regards to Subside, be weary that they only do the name and numbers of certain players. For example, I wanted J. Zanetti shirts and all they had are Figo, Adriano and Ibrahimovic. Personally, that pisses me off so I opted for Inter Store and both of my Centenary shirts are J. Zanetti # 4.
