Shares all items currently available (6)
I believe the answer is:
stocks
'shares' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for stocks that I've seen before include "Securities, investments" , "bloomers" , "Keeps" , "heavily-scented flowers" , "Village greens used to have these" .)
