I am working on my install and started a trial of ActionTiles last week, so I didn't need a licence yet, but when I was logging in today, I noticed that there's a 24% off coupon, so I just bought my license. I figured I'd give a heads up to anyone else interested. Price is normally $28.99 for a location (hub) and right now with 24% off that brings it to $22.03.
