PC - Various Items

Just some simple blue items that are taking up inventory space, I am not sure whether to sell to a merchant or find a buyer for the items in the picture below. If someone could give me a price range for these items, I'd be most appreciative. Thanks

For identified runes check the rune trader prices (sell for less than at trader & more then what you get for selling to trader).

Elemental upgrades are around 500g (exception fire strings which go for more), Zealous axe shaft 500-1k.

20-21hp upgrades 250-500g. Not sure on +1 weapon stat upgrades & armor upgrades.
