iTronics via Walmart offers the ThermoPro Thermometer and Humidity Monitor with Jumbo Touchscreen for $12.99 with free shipping. (Amazon charges a buck more.) That's tied with last week's mention and the lowest price we could find by $5. This hygrometer features a 4" backlit touchscreen LCD and provides real-time readings, all-time high/low records, and current trends for both humidity and temperature. Two AAA batteries are required (included).
