Home Depot offers the WBM Extra Large Himalayan Ionic Crystal Natural Salt Lamp, model no. 1002, for $12. Choose in-store pickup to dodge the $6.74 shipping charge. That's $11 below our mention from last week and the lowest price we've seen. (It's a current low by $3.) This lamp features a 15-watt bulb and dimmer switch. It purports to function similarly to an air purifier. Deal ends December 8.
