The latest Ecobee has been released and certain utility companies are offering $50 instant rebates. It's basically a new Ecobee4 but with upgraded components and a glass screen instead of plastic. I had been looking for a deal on an Ecobee4 and didn't even realize a newer version had been released. I was pleased to see that I was eligible for an instant rebate through BestBuy's website!
Price will be $249-$50 = $199, and depending on your state possibly plus sales tax. Shipping was free via BestBuy.
The only pain is making sure that you enter your utility information EXACTLY as they have it. I even had to use all capital letters because that's how it's printed on my bill. After being "approved" you'll select which merchant you'd prefer to use, and then get an email with a coupon code that you can enter on that merchant's website.
