Knoz aero back pack

The one good thing at the excel show was the R&G stand where I managed to get this back pack for £25.00 (my local dealer has them for £65.00!) thought I would get another one as a present so went to planet-knox http://www.planet-knox.com/detail2.aspx?ID=63 where they are selling them for £29.99 but no shipping costs.
