iTronics via Walmart offers the ThermoPro TP55 Indoor Digital Thermometer and Humidity Monitor with Jumbo Touchscreen for $12.99 with free shipping. That's tied with our mention from a week ago 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.
