Found this when I was hunting for a way of sending post that was bigger than Post Office permit, turns out to be quite competitive and uses multiple couriers to achieve different price / size points.
May be useful for some of you or alternatively you may have your own favourite company to do this, if so please share as I am sure we will all have something at some point that is easier collected from home to be sent.
Good link, I tried a few quotes today, not bad pricing.
