This was posted earlier in the FSX Sales thread, but just in case anyone interested may have missed:
Milxiz is having a 30% off sale on all aircraft for three days only until Sunday Sep-16, both at their store as well as their
third party retailers (already up at Simmarket, I assume others will follow shortly).
