As one of its daily deals, DealGenius offers the Honeywell 7-Day Programmable Thermostat, model no. RCT8103A, for $19 with free shipping. (That Daily Deal charges a buck more.) That's a buck under our mention from yesterday. $41 off, and the lowest total price we've seen. It features a large backlit display, separate weekday and weekend programs, continuously adjustable pre-heating and cooling settings, and auto-change function. Deal ends today.
