Good morning, @bizarebazaaar
If you would like help from eBay specialists, you are in the wrong place. This is a member to member discussion forum where eBay staff will not deal with individual issues anymore.
As of 8:04 Eastern time in the US, you have 870 or 877 items for depending where I look on your listings page. I do not know if there are more items you are selling that are NOT offering shipping to the US , or you are thus missing some because you are logged into eBay US at the moment.
There is some link disconnect that occurs for many UK users that redirects them to the US discussion boards all the time. People here help if they can, but you might find better assistance by posting to the forums in the UK. That way you can determine if it is a domestic problem related to your site, or other problem.
