When you use the pricing lens on 99 iron tipped, oak shaft, owl feather arrows it says a little over 8000gp. I have seen that same bunch being sold for 1500gp to 2000gp. Others have offered what amounts to about 2gp per arrow 200gp per bunch. Zero' s guide does not address this as of yet, it would be great if it could be included in the next draft. I myself will go with 25% of the lens price, which is 2000gp if in trade. For a gold transaction I would go 1500gp.
