For those interested, DCS is making a major change for new players. As of Sunday February 25th the "First time purchase 50% off" deal will disappear. This deal allows first time purchasers to get 50% off their ENTIRE purchase. Whether you buy one aircraft/map or ALL of them, you get 50% off.
If you have considered trying out DCS, you might want to do it before Sunday. There will still be sales several times a year and they say there will be a new type of deal offered soon, but this is a great deal.
