Following in the wake of the first pre-order discounts on the new iPad Air, Best Buy is now offering an exclusive $50 discount on the M4

The biggest discount of $550 comes if you have a MacBook Air M3 to hand over, but you also get $500 for the M2 version and up to $300 for a MacBook Air M1. Additionally, Best Buy Plus and Total members get a further $50 off, potentially bringing the price under $400. This is one of the best MacBook Air deals we've seen in a long time.

In Geekbench, which measures overall performance, the MacBook Air M4 hit 3,751 in the single-core test and 14,947 in the multi-core test. That’s 21% faster than the MacBook Air M3. The dual-core result was 23% higher.
