One of our education partners, Ergo, have just told me about the competition they are running at the BETT Show in January. If you visit their stand (B100) in the main hall, you can enter their college prize draw to win an Ergo SecureDesk.
Of the 30,000 visitors to the BETT show, only about 1,000 are from colleges - and this prize is only for them. So if you are going to the show, then the odds are probably good! I haven't heard about other competitions (yet) at BETT, but I think this has got to be worth including on your "must visit" BETT list.
