Is there a way to block sellers when searching?

If not it should be a feature added. 

I sometimes buy things where a seller seems to dominate the search results. I've used them before, but they are not truthful about item location and eBay doesn't care. The last item shipped out of China when the listing said it shipped from Kansas

Yes, there is a way. Go to Advanced Search. Toward the bottom of the page is Sellers. Change the dropdown from Include to Exclude and enter the seller's ID in the box. After you do the search you can save it and run it from your saved searches to avoid having to go through the process each time.

You can block up to 10 sellers' items from showing up in a search result using the filters in Advanced Search or in the left column of the search results page (More Refinements: Seller).  You find the filter where you limit the results to those of given seller(s) and change the "Include" to "Exclude" and list up to 10 IDs in the following text box.

You can then save the search (link towards the top left of the results) and then access the saved search in My eBay: Saved Searches (you'll probably want to turn off notices of new listings while you're there) changing the keywords and other filters as needed to find what you are looking for.  You can save multiple searches with up to 10 sellers excluded in each to use for searches in different categories (or other way to distinguish which set of sellers is most likely to have listings in what you are searching for).
