I haven't sold too much but i don't find the experience stressful. I did find it time consuming but i also enjoy a making a buyer happy with a package i send - i get a genuine kick out of that.

For me, i have to be picky with what i can afford and when. I find the extra few dollars of postage usually turns me away from buying items. I also find it hard to ask for a lower price as sales are often reluctant and brought about by hardship. Every deal is different and for the most part i see a lot of great things for sale but i can't buy on a whim so i move on and read another thread.
