In the latest Maplins flier there are 2 bargins, I think.
There is a usb bluetooth dongle, just plugs into any usb slot for £19.99 comes complete with software. Great for PDA's. I have just got one for a Sony clie, installed it in seconds and communicates very well.
Also there is a Irda desktop sensor, USB cable and software. This is also on sale for £19.99. This is great for some Nokia phones to communicate with the P.C.
