Having trouble finding cheap furniture? Sick of bargaining prices for dodgy futons on Boards.ie? Why not try Dublinwaste.ie instead. It's kind of like an online recycling centre for furniture and other goods. Everything on it is free, though most of it is pretty crap or doesn't have a picture with it. Every once in a while, though, you find some pretty nifty stuff like this grey wardrobe (I'm certain that it must look better in real life).
Or this storage unit, though this might look better in a larger apartment or house.
A few months ago someone was getting rid of an 1960's rosewood sideboard! I was so close to nabbing it before James reminded me that we had no car, and therefore could not go pick it up in Cork. Even if you do have to hire a van or pay a friend with a car to deliver it for you, depending on the item, you'd still be saving loads of money. In the case of that sideboard, I would have saved about €1000 (price compared to that of Wild Child Originals and Habitat 20th Century Collection).
If you fancy a little upholstery project, you can pick up one of many ugly armchairs and sofas the site has to offer. Some of them have fantastic shapes but disgusting colours and patterns; all they need is some new fabrics for the perfect pick-me-up.
