Best Buy slashes $100 off iPad Air 2 (from $399), $200 off MacBook Pro with CD/DVD ($899), $150 off iMacs (from $899)

After being teased on Wednesday, Best Buy's Black Friday iPad Air 2 sale is now live, as can be seen in our iPad Price Guides, with 16GB Wi-Fi models in all three colors going for $399.99, while the same capacity with cellular LTE starts at $529.99.

While Best Buy plans to keep its sale running throughout the day, stock is not guaranteed, especially at such low prices.

Update 7am: Best Buy's stock of WiFi models is already beginning to sell out, and those in stock are not guaranteed to deliver until Dec 10th unless you pay another $16-$30 for expedited shipping. Couple that with roughly $30+ tax collected on each sale and your net price may be higher than purchasing from some alternative resellers, like MacMall, which is selling the same models for $40 off with free shipping and no tax collected on orders shipped outside (CA, CO, GA, IL, MN, NC, NY, TN, and WI).
