Unit/medic Refund?

[JohnnyR]

So today I've been raidng and attacking left and right and have been trying to meet my next defense goal and have been buying medics. One by one....and then I notice a tick up in my money. It turns out every medic I'm buying gives me back 2k. Not sure if I've even made the right connection between events here, but as that's the only unit and thing I'm doing, I think they're related. My bro is experiencing the same thing. This part of the 20% off sale or what?

When I buy a medic, my funds go down 18,000
