True. Maybe the OP thought he clicked auction or another option and then confirmed?
Everyone is saying to do the right thing and sell. I agree but I wonder if folks would change their view if it was a LLL and "sold" was clicked at $60 by mistake?
So far as two clicks, I was up early in the morning and going through my emails, saw $75 and though "sure I'll take it" without much further though...until I'd had a coffee. Now my rule is to never respond to offers until I've walked away from the computer and had time to think. But, yes it's possible to make a mistake that requires more than one step.
Point taken about the LLL, but I don't get the impression from the OP that it was quite that bad. It's money he could use, sure, but it's not a disaster - at least that's the impression he gives. If I were the buyer and got a $60 LLL from Sedo, I would be expecting the seller to cancel out!
Selling an LLL for $60 is an extreme example. The point here is that standing by your mistakes both protects your reputation and is essential for self-respect. I regret a business deal I did when I was younger...little compromises that added up and put me in a position I hadn't planned on. Each compromise was entirely explainable and even excusable, but once you have to explain and excuse your reputation is already shot. And in the end, trust is the most valuable thing you can offer in business.
Nobody's perfect, and you never know what even the most reliable person might do when put in a real squeeze. But at least doing the right thing where it doesn't wipe you out, but just hurts a bit, is the least anyone should do.
I've seen people with stellar reputations burn it all when faced with total financial disaster. But, for a couple hundred dollars? No way.
