also, dont forget to look up your local 'freecycle' group.
you can ask for stuff, rather than having to check every day and seeing what is being offered. i think they would like you to loffer something first, before you put in a 'wanted' ad. i have gotten rid of a number of things i wouldnt have been able to give to charity shops (TV, stereo system in perfect working order) and have asked fro wine making stuff and will be picking up quite a few things next weekend :)
