A recent addition to the Free Gift board is the Mystery Shipment, which provides the recipient with a "needed" upgrade part for a Property. The icon on the Free Gift Board is at the upper left:
Sending these to your Mafia, and receiving them back, is a good way to get upgrade parts you need for Italy (as well as, I believe, your Chop Shop, Casino, etc.).
But if you're focusing on Italy, you can obtain the hard-to-find Terracotta Tiles from Mystery Shipments... though I recommend you try this trick first if you really want to load up on the Tiles and the Stone Columns.
I was admittedly confused when I started receiving THIS upgrade part - the DJ - from Mystery Shipments. What property requires a DJ??
Hat tip to "dmon" and an Anonymous commenter, who deduced yesterday that the DJ must be the unique upgrade part (like the Wine Barrel or Football Player) to the Village Property that we HAVEN'T gotten yet - it's circled in red, below, on the picture of the completed Italy Village that Mafia Wars posted just before Italy went live.
As the commenters noted, if the unique part is a DJ, the Property will be a disco or nightclub of some sort. So we can expect this to be a new Village Property when Mafia Wars releases Italy Region 6, Region 7, and Region 8 down the road.
This is reminiscent of how Mafia Wars unveiled the Fountain in the Las Vegas Casino when it released the final Districts in that city.
There is a limit of Mystery Shipments you can receive per day.
