I'm very up for buying 2nd hand / used / preloved. Furniture. Clothes. Bigger purchases.
REALLY irritates me though when someone is selling something large. Piece of furniture. Climbing frame. Kitchen. Conservatory. They want paying a reasonable amount for it, BUT they also want you to take it apart unaided.
In effect, you are paying them for the privilege of removing it for them!
Saw an advert today for both a kitchen and a conservatory. Both want the buyer to remove, take down and take them away. BOTH want a not inconsiderable payment for this.
IMO, if you want to sell something big, you need to be prepared to at the very least assist in breaking it down. And IF you don't want to do that, you probably need to offer it for free. (I'm not after a freebie here. I don't want the kitchen or the conservatory.)
