Today is the last day of the Summer Giveaway and you can grab a free Nebula Retrofit for Fed or Marauder Flight Deck Cruiser for KDF from the C-store in game. The only catches are the characters claiming the ship need to be at least 40 and have an available ship slot. Once the ships are claimed, they're yours just like any other ship purchase via the C-Store so you're saving at least $20 (I think). It looks like the previous 4 days items are no longer available for free, but these 2 ships still are.
"These FREE account-wide unlocks must be claimed by Monday, August 19, 2013 at 10AM PDT when they will revert to their normal prices."
