Little Snitch for MacOSX discount code

I have been wanting to buy this software for my Mac for a while now but always have been put off by the steep price (29.95). Now, I found a discount code for 35% off the software bringing it down to less than 20 bucks!

Code is DT-7A8B-7BC2, get the software directly from the developer's website at www.obdev.at
