Two sites definitely worth checking back to every few weeks are Retrouvius and Re-Found Objects. Retrouvius has carved an interesting niche for itself by bringing reclamation to the web. At the moment they have a whole load of Ercol chairs salvaged from a convent! And, for when we all get seriously wealthy, they also do interior design!
On a much more humble note, I can indulge my new penchant for poached eggs with these cute poachers from Re-Found for just £5 each!
