MegaMacs offers the refurbished Apple iMac Intel Core i3 3.2GHz 27" Desktop, model no. MC510LL/A, for $799.99 plus around $30 for shipping. That's $90 under our May refurb mention (which featured half the RAM of this unit) and the lowest total price we've seen for this model with 8GB RAM. (It's also only a buck more than the best price we could find for a refurb with just 4GB RAM today.) Features include an Intel Core i3 3.2GHz dual-core processor, 27" 2560x1440 (1440p) LCD, 8GB RAM, 1TB hard drive, Radeon HD 5670 512MB graphics, SuperDrive (DVD burner), AirPort Extreme (802.11n wireless), Bluetooth 2.1+EDR, and Mac OS X 10.10 (Yosemite). Deal ends September 30.

Note: A 90-day MegaMacs warranty is provided.
