Wanted to expand, but no discount available, so I just bought a brand new system at 60% off
It was significantly cheaper to buy a new system with 60% off than to pay full price for the add-ons I wanted (various new sensors). It was even cheaper than their 40% off system extensions deal a week or so back.
Why would they do this? They ended up spending more money because they had to send me a new base station, key pad, and free camera while charging me less.
