As one of its daily deals, Woot offers the factory-refurbished Porter Cable 6-Gallon 150-PSI Oil-Free Pancake Air Compressor, model no. C2002, for $69.99 plus $5 for shipping. That's tied with last summer's mention as the lowest total price we've seen for any 6-gallon pancake compressor. (It's also $47 under the best price we could find for a new unit.) It weighs 34 lbs. and features a low-amp 120-volt motor and two air couplers to support two users. A 1-year Porter Cable warranty applies. Deal ends today.
