THEIR ADS ARE MISLEADING, THEY DON'T STAND BY THE ADS, THEY JUST HANG UP ON YOU! They advertised a Monday night 24-hour sale. There ad said "Heat 1500 square feet for $1 day $239.00. I could not find on their website a heater that would heat 1500 sq. Ft. For $239.00. When I asked the rep on the phone (after waiting on hold for 15 minutes) he replied, "Oh, you're an ad guru today", then he abruptly hung up. There ad was not true, and there customer service sucks. I would not order from a compnay that treats me in this manner BEFORE the sell. Just imagine what it would be like after the sell.
