There is currently a special offer on the Vax.co.uk site, where all the '30th Anniversary Range' of vacuums is reduced to half price. There are 2 cylinder models (both £59.99) and 4 upright models (£49.99, £64.99, £84.99 and £124.99) and 2 carpet cleaners.
These all seem to be much cheaper than equivalents in other stores so I think it is a genuine 50% reduction! I.e. Power 2 model lowest is £79.99 on other sites, this is the 'power 2 anniversary' model (same spec, different colour) and it is only £49.99 here.
p.s. something rather random but funny... check out the home page http://www.vax.co.uk/
and watch the flash ad for the new model. Everything is perfectly normal until the end, then for some reason a small dung-beetle wanders onto the screen and rolls the 'MachAir' logo across the screen like a ball of dung... very odd.
