If you have specific items that you don't see in our listings, please feel free to send us your WANT LIST! 
There is a very good chance we can help you for several reasons:
One reason is that we don't have ALL of our items listed here at ebay (not even close by a longshot!!!) 
the inventory is truly THAT EXTENSIVE so listing it all one-by-one is impossible.
Secondly we have an extended partnership of direct sources so it enables us to have a "wide reach" to
obtain the harder to find items that you don't have the time to devote to the task!
