So I'm guessing that since this is Rakuten, you won't be paying state sales tax, and due to that you won't be eligible for a $100 rebate from the state (from Comed since I'm in IL).

I don't think I have a C wire. Is that a dealbreaker for the nest? Any realistic workarounds? They say you don't truly need one, but I've seen people comment it will run the hvac just to get power, which I don't want at all.

Thanks! I've been waiting for a deal on one of these. Used PayPal in case the seller I used ends up being shady.

I believe it works by the internal battery being charged when the system is running. It doesn't require very much power anyways, so I think when the system is running will be plenty to keep the battery charged and the system won't have to turn on just to provide power to the Nest. I'd love for someone more experienced to answer this as well.

Also, I have an older gen Nest without a C wire and haven't noticed any odd behavior. I'd also like to verify that this is true with the newest gen. I was considering an Ecobee because of the external sensors, but now that the 3rd gen Nest has sensors, I may go that route since the C wire isn't required.

Anybody have experience with how well the sensors work? I have 2 poorly placed thermostats in my home and would much rather use the sensors to be the primary temperature sensors depending on different times of the day.

If you notice at the top of the website, this is a site-wide deal. So I'm guessing the 15% off can be used pretty much for anything. E B A has 2% cash back, but Mr.Rebates has 4% cash back, so use that in conjunction.

you will need a c wire. i bought one and installed it in one home where there was no c wire and the heater would start, stop, and start, stop repeatedly to no end.

The sensor works great. I have it set so that it uses the sensor on the second floor (bedrooms) between 8pm and 6am and uses the main thermostat all other times. You can schedule it anyway you want and it works perfectly for us.

We also don't have a C wire and haven't had any issues in over 8 months with the main unit. We did initially charge it up using a micro usb cable and seems to be enough current to keep it going with the brightness turned down a little bit.

Look at the Nest.com website. They have a compatibility page. that goes into the different wires. I installed two this past weekend. Simply and easy.

It advertised as not needed and you certainly don't need it but ymmv. It's not a straight answer as the c is needed or not. I don't have one in mine and all 5 nests work fine.

Most AC system provide enough power when on to not need the C wire. In rare cases it will be required. YMMV

As others have said, in most cases it seems to work without a C wire. Take note of the wires on your current thermostat and use Nest's compatibility tool:
