Best Buy offers the refurbished Apple AirPort Express 802.11n Wifi Base Station, model no. MB321LL/A, for $49.99 with free shipping. That's $35 under the lowest total price we could find for a new one, although we saw a refurb for $16 less in January. Sales tax is added where applicable. The AirPort Express uses 802.11n to play iTunes over your wireless network to your home stereo. It also acts as a wireless router and performs wireless USB printer sharing.

Of note, this item does not carry a warranty, however, a 30-day in-store / online return policy applies.
