Bright Byte, I have sold in the past (nothing to compare with others here) .Now I just buy.I try to  see things from both sides and to treat others as I would like to be treated...though remembering that what is happening is a business transaction ....as a seller it was very much in my best interest to do so.

As a buyer it is over for me when I received what I paid for.It is mine.End of transaction....anything else I do is up to me .

If there is a problem a seller can rest assured that I will let them know...even if I haven't left feedback and/or left it in a time frame they think reasonable.
