So I recently went through a difficult trade and decided not to include extras and the guy sure let me know it when he received his package with some not-so direct comments. But this was the same guy that took his sweet time to answer every message...after he finally accepted the initial trade. In the middle of the trade he decided he wanted something different. This trade had taken close to a month just to get the package out the door. Somewhere in the middle I just wanted it to stop, but I continued to chop through the trade because I was already committed and I worry about my reputation, though small. I doubt I would have ever heard from him again if it weren't for the lack of extras! I personally, normally, base my extras on my interaction with the trader and the communication exchanges; were they friendly? responsive? type of trade, good/fair trade or one sided? etc. Now I know extras aren't mandatory, but maybe this can serve as a reminder! Thoughts?
