I once bought a swing set on FB. Seller "It's quite big, are you definitely able to collect it? It's just I've had problems with other buyers." Me "I've got a van and a trailer and I can be there later today or tomorrow. Will you take 150? (It was up for 250 - I'd have paid 200)." Seller "If you can come tomorrow morning before 11 I'll take 50." Arrived at 1000.
