Friends of ours recently moved houses and downsized considerably. Through neccessity they had to cull a lot of furniture and household goods. They called one of the charities (don't know which one) and said they would like to donate a lot of stuff. Said charity "ummed and ahhed" over the phone and finally said they would send out their big truck with a couple of guys, but if they found that some of the stuff was crap or there wasn't enough stuff to fill the truck they would pass on a $60 charge to cover their costs.
Our friends said they would get back to the charity. They decided it was simpler to just wheel the stuff out to the kerb and within 24 hours it was all gone.
Seems it's getting expensive now to donate stuff for free.
