This 54Mb wireless ADSL router is currently reduced from £69.99 to £49.99 (save £20!) and includes a free USB wireless adaptor. Also, if you buy it before the end of the weekend, spend a penny more on another item, and get a free £5 Argos voucher to be used in the next few months.
Bought one of these this morning, and am now typing this using my laptop and wireless! :)
