What I find amazing is how people offer me 50% of my asking price, and when I counter, if they know how to get ahold of me, they say my price is way too high, only to see it sold at my full asking price a little while later.
I don't mind offers at all. I will accept some offers of 50% but will counter the rest of them, unless I have countered a few times already.
I don't think anything can be priced too high within reason when it can sit there for 12 cents per year until it sells.
One thing's for certain, I have never been disappointed with even a single sale I have made. How many people can say that when selling on Ebay?
