You are still not understanding! I manage my inventory outside of ebay and pay good money to do so. This means i do not use the ebay inventory tool as this to me would be double handling. So everything i have is listed and a large amount so i do not have to relist because i sold too many. I get emails telling me an item sold and i need to keep checking that the item is still listed.
I have done this for about 4 years without any issues and 95% of buyers are happy to wait. My feedback was 99.6, do you realise what this means? And on top of this, i was not selling 5 items per day like yourself so as your business grows it becomes more time consuming and more difficult to manage.
I would love to have the time to review every ebay policy that comes out, see how this affects me and take action but unfortunately i dont.
