The HealthSmart 500 mL essential oil diffuser in white (model 40-500-190) is $7.57 new at Woot, versus $19.95 at Walmart and $33.99 on HealthSmart's own site. It doubles as a cool-mist humidifier with seven LED colors, a 1, 3 or 6 hour timer, and auto shut-off when the tank runs dry. Woot limits it to 3 per order and stock looked low.
