Posting details about this model as it is what I looked at (was comparing it to the Lidl washer) however they are all reduced instore - plus there is currently 20% Friends and Family discount (ask a member of staff about this).
K2.300 T50 - reduced to £104 plus 20% off (these are £149.99 @ Argos).
The next model up was reduced to £170, again you can get another 20% off that.
Have pinched the info for this washer from another website - we personally went for the Lidl one, but I know some would prefer to stick with Karcher make. These come with 2yrs warranty btw:
