Use of condition grades is meaningless to many buyers who are not collectors.
The grade should be consistent in each listing. VG+ in the title and Fine in the description is an invitation to disaster. Most non-collectors expect a Very Good condition item to be Very Good which booksellers and collectors use when the condition is not particularly Good.
See image for condition is a cop out, safely used when you have identified major defects in the condition notes or identified the condition as poor or acceptable.
Much of what you and I sell only sells to people who have a strong desire to own the item. I have few issues with my buyers about condition. Maybe the 99% of my buyers have only left so few good buyers that only 10% of the good buyers are available for you.
Maybe you are attracting ungood buyers by accepting offers on almost all of your listings. My buyers pay the published price and the cheapskates and marginal buyers search elsewhere for a bargain.
Buyer psychology is complex. I like most of my buyers, particularly the repeat buyers. But I do my best to discourage certain buyers.
I also have a different standard for my images. They are usually scanned. They are closely cropped. And they are of sufficient resolution that a buyer could use them to know the condition if I did not describe it. No rulers in my images. I measure each item for sale.
You are not a newbie. You have success on Ebay. It could be that life could be more pleasant by improving your listings. Feeling that only 10% of your buyers are good buyers must be painful.
