If ebay is your future and you want to make it a business then feedback would be important so its not woth risking negative on the sale of a small item

I have never, and never will, based any decision about what to do on what feedback I may receive.

I do what I consider to be the right thing and if a buyer chooses to disagree and leave me a neg then they can.

You only have to look at all the threads on here from buyers who have problems after they purchased from a seller with lousy feedback and DSRs to know that having a couple of negs does not mean you are going to sell less.

As a buyer I am perfectly happy to buy from a seller with one or two negs as long as they have handled them in a businesslike manner and not written nast follow ups calling the buyer names, in caps!
