Comet are currently doing a promotion where you get 20% off ANY Dyson when you trade in ANY old vacuum cleaner.
A great deal if you are considering buying a Dyson, and it probably works out better than the Argos deal as there is no gift-card involved, this is a straight deduction at the till.
*Please no bad mouthing Dyson like I have seen in another thread, if you don't have anything positive to say, don't say anything at all. I think it really puts a lot of people off posting deals due to all the negativity in certain threads. If you want to buy Miele or Sebo, look elsewhere.*
Offer ends 14th of August.
