Weekend discounts on Apple's personal computer family continue this month, as Apple works with partners like big-box retailer Best Buy to push sales of Macs in the face of weak global demand, and a bearish outlook for the consumer PC business in general.

Both Best Buy and Amazon have cut MacBook Air prices by $100 and iMac prices by $150 for Mother's Day. They represent the lowest prices ever on the new 21-inch iMac models, and the lowest overall prices on MacBook Airs since January. Both deals are expected to end late Saturday and are valid on Apple's standard retail SKUs.
