Buying damaged or imperfect household appliances

Has anyone ever bought a physically damaged household appliance from a retailer before such as a fridge freezer, washing machine etc?

An appliance that, for all intents and purposes works OK but is physically damaged or visually imperfect.

How was the experience? Worth doing or a false economy?

Any links to retailers who specialise in such goods?

I may need a new fridge freezer and looks like there are no decent deals about at the moment so thinking of going down this route and getting something 'decent' when a deal appears and selling on the imperfect one thereafter.
