Need furnishing for new flat on the cheap!


Hi all,
I will soon be moving into a new flat with my girlfriend here soon.
We have to fully furnish it and have some stuff lined up but would like to know where i can get things cheaper, if they had to be 2nd hand that would not be a problem.
I see there are times on this site that people have to leave or re-move so get rid of there things for a good discount and it would be excellent if I could take advantage of that but would also like to know if there is other alternatives either around the city or on the web.
Thanks for any help or advice.
