Sell local.
Use something like Kijiji or whatever alternative you have for your area.
No shipping fees, and you can usually get the sort of "I want it, I'll buy it if you hold it for me" sort of people.
Then again, I don't know where you live. You might be in a small town from Bhutfu'k-Noa'er.
I don't remember you ever stating where you lived, and I'm not gonna press for that information.
Buy and sell cheap and local. Saves postage, keeps civility too, especially if the individual wants to know it works, or you both know it works when it is being sold.
Stops scamming and stuff. I really suggest buying and selling local.
Mega conglomerates like Amazon, EBay, etc., they can all eat-a-dick, shafting everyone at every turn.
Local. It works wonders usually.
