MegaMacs offers the refurbished Apple MacBook Intel Core 2 Duo 2.1GHz 13.3" Laptop in White, model no. MB402LL/A, for $299.99 plus around $17 for shipping. That's tied with our June mention of this configuration and $88 under the lowest total price we could find for a used unit elsewhere (this one's refurbished), although we saw a refurb with half the RAM for $27 less last week. Features include an Intel Core 2 Duo T8100 2.1GHz dual-core processor, 13.3" 1280x800 LCD, 2GB RAM, 120GB hard drive, DVD burner, iSight webcam, AirPort Extreme (802.11n wireless), Gigabit Ethernet, Bluetooth 2.0+EDR, and Mac OS X 10.7 Lion. Deal ends July 31.

A 30-day MegaMacs warranty applies.
