I bought some lights from smudge last year. The battery failed, so I sent it in to be fixed. It didn't arrive, so smudge sent me a new battery FOC.
More than that, I submitted a lost parcel claim through Royal Mail and they *eventually* paid up. WHen I asked for smudge's details to send the money on he refused and insisted I make a charitable donation. £15 each for Help for Heroes, my local Air Ambulance and my local MRT.
On a similar note, we went to Revolution at the Manchester Velodrome last season when IHN offered us "spare" tickets at cost price - he'd bought season tickets but upgraded to the VIP area for the first round. As he hadn't checked his diary properly when buying the season tickets, he was unable to make the next two rounds either so we got to use the season tickets in return for a (sizable) charity donation.
