So back when SS was in closed Beta, Playfish had this thing where certain numbers of likes of Sims Social page unlocked free items. This ended about a month or so ago, but now they are allowing Simmers to get the free items again. Today is the Liebefunkenmann SS-10 Keyboard. Now if you’re like me and already got this for free, get it again. You can always sell it and have extra Simoleons.
Keep checking their page as they will eventually be offering the other 8 items for free as well.
