When I really break a sweat is when I have someone win one of my auctions and then not pay right away. It sucks not knowing if they are going to pay, especially since I know I am going to have to pay for selling it. Then if they don't pay after I wait two or three weeks I have to finally repost it for sale and then worry about them contacting me wanting to know why I am selling something that they have already won.

Just because they were thinking about buying it I ended up having to wait an extra three or four weeks for money plus it cost me extra money and stress.

Anyway, it's sorta nice having feedback around the 250 mark with 100% positive feedback.
