Bear in mind that for heavy lower value items, the postage cost can make it prohibitive to buy - eg if you sold a toaster for 99p, the postage oculd be �5, making the total amount spent by the buyer more than you can buy one in Tescos.
Those are only example figures, BTW!
So for times like that, where you just want them out of the way, what about Freecyle? There are groups all over the country, stuff is offered free, people who want it respond to your email and come & collect it, job done.
Excellent for larger things like furniture & kitcen equipment, if your fridge has a dent in the door it may not be saleable, but it still works & could be very welcome to someone whose fridge has just died.
Currently on our local group items offered include kid's toys, men's clothes, office furniture, crockery, plants, christmas tree, printer.
