Cheapest I've seen for the Vornado 660.
Available in both black and white for $139.
Edit:
Found the Vornado 633DC white for $139 as well. See here

don't forget Shopback. "Home" is still one of the eligible categories at 5.3%. Mod: Removed as users reported tracking at $0.
That's a really good price. Cheaper than Costco. I think they are over $150 now.
