Walmart clearance YMMV - GE Z-Wave Smart Switch and Dimmers $15
My local Walmart had GE Z-Wave smart switches on clearance for $15. These were in the clearance aisle. They were both the on/off switch model 12722 and the dimmers 12724. I own several of these already and they work great with SmartThings and Alexa. They normally sell for around $40 so these were a steal and bought all they had left. This is definitely a YMMV deal but if you can find them it's a steal. I assume they are making way for the newer Z-Wave Plus switches.
