Look for an email with this in the subject: [FINAL NOTICE] Nest app support for your Nest Learning Thermostat (1st/2nd gen) ends Oct 25

I have 2 2nd gen nest thermostats. I received the promotional discount for a 4th gen but it only allows me to buy one 4th gen at a discount. The second one is marked at full price. Can you send me a discount code so I can purchase a second device?
