Was watching an item on ebay, £10 plus £7 P+P. Completely forgot about it and it ended bidless. Had a look at the sellers history and it had been listed several times before (and not on weekends either so these were paid listings).
Messaged seller, said 'sorry, I forgot to bid, would you take £15 including P+P and I'll paypal you directly to save fees'. Seller says no, £17 or nothing. I said no thank you and bought elsewhere, ironically for less.
For the sake of losing £2 he's now relisted for the fourth time and will pay FVF. I'm eagerly watching the item not sell this time as well. 
Can't see his profit margins being great TBH.
