there is a little trick for these to always know the price..
go to the rune trader
look at the price of the rune @ the rune trader (the BUY price)
then click on the "sell" tab
look at the price of the rune @ the rune trader (the SELL price)
add those to eachoter (lest say: 5k + 3k = 8k) then divide that by the magic number: 2
You might get 30g for it, the runes that make money are superior absorbtion, vigour and a few warrior and monk items. There isn't really a market for superior ranger runes im afraid.
