I just endured a couple of weeks of angry emails from a fellow in another country who bought something from me at eBay (a $200 Japanese tin toy, probably a bargain at the price).
Before he bought the Thing, he asked me if I'd falsify the customs declaration on the package so he could avoid some duties in his country. I promised him that I would not do that.
He bought the Thing. When he paid, he asked me to reconsider - he explained that his duties would be expensive. I again informed him that I would be accurate in my declaration for a variety of reasons including my reputation for honesty and my desire for the customs declaration match the insurance amount I was buying.
About a month later I received an impatient where-is-it question. I looked at the same tracking that was available to him and told him the package had arrived in his country four days after I mailed it, and it was being processed by customs. I suggested that he might want to contact them, since that action has shaken loose other packages in other countries when the same thing has happened (I have sixteen years of experience in International shipping).
His anger escalated - he could not be bothered with all that. He paid, he didn't have it, he was unhappy. Next came the PayPal claim which disintegrated when I provided the tracking information.
Today, he let me know he was on his way to his post office with $75.00 in hand to rescue his package. He's still mad. He'd just like me to know that "maybe a next time you can do a little bit better with offer lower price."
I was surprised to discover there isn't a category for that problem in the eBay report-a-buyer system.
I don't see a lot of discussion about folks like him, although I quit using eBay forums five years ago. If eBay is truly concerned about being a little kinder to sellers, I have a suggestion to make...
