I've used Freeycle many times - gave away a Halogen oven, small suitcase, rucksacks, straw baskets, 2 side tables, kitchen equipment and lots of other stuff. Picked up an adjustable mannequin, a shoe rack and a stool.
I always ask the first responder when they will collect and tell them if they don't pick it up then it will be offered to the next person that asked. I usually ignore any immediate responses though (unless they are the only ones) as they are usually people who respond to everything while they debate if they actually want it and then ignore you.
