Ending today, MacMall discounts over 500 items — including Macs, iPods, digital cameras, accessories, and more — up to $649 off as part of its Grand Opening Sale. (It opened a new store in California.) Although it's among the largest sales we've seen from MacMall this year, several items can be found for less elsewhere. (We listed a sale with up to 85% off select products on the Cyber Monday, since expired.) Shipping starts at $5.99, but orders of $25 or more qualify for free shipping.

A best bet is the the 2.9-lb. Apple MacBook Air Intel Core 2 Duo 2.13GHz 13.3" Notebook (pictured), model no. MC905LL/A, for $1,098.99 with free shipping. That's a $50 drop from last week's mention and the lowest total price we could find, this time by $62. This previous-generation model features an Intel Core 2 Duo 2.13GHz dual-core processor, 13.3" 1440x900 LED-backlit LCD display, 4GB RAM, 256GB SSD, NVIDIA GeForce GT 320M video card, webcam, 802.11n wireless, Bluetooth 2.1+EDR, and Mac OS X 10.6 Snow Leopard (with free Mac OS X 10.7 Lion upgrade).
