While all Clearance is YMMV, as you can see from the attached pictures, they had quite a lot of stock left.
There were several makes and models, ranging from small under-the-desk fans with a heating coil to the oil filled "radiator" types.
I've included the "radiator", DCPI 085-19-102 type in the attached photos, originally $50, it's marked down to $15. I almost bought one, and I have no need for a heater at all (It's February and I'm still having to keep the AC on. Crazy...)
