Apple has quietly slashed the price of AirPort Extreme cards.

According to online price comparison services, the cards were formerly priced at between £49-£53 each. They now cost £30 (including VAT).

The AirPort Extreme Card lets AirPort Extreme-enabled Macs communicate with local wireless networks. It works with all earlier versions of Apple's AirPort Base Station as well as the AirPort Extreme Base Station and Airport Express.

The wireless standard offers data rates of up to 11Mbps.
