I came across an Aerosoft Sale for 4th July on the Flight Sim Store site, which may be of some interest. Appears to be mainly P3D/FSX though, so didn't blow my skirt up as i'm now exclusively on MSFS2020, but might be worth a look if you are on one of the other platforms

Also, Orbx also has some really good deals on selected sceneries so i managed to pick up EGHI (finally), although its not patch on the FSX version i used to love.. V2.0 maybe??
