90k for a 1k arrows stack isn't expensive. It would mean around 9k for a 100 arrows stack, pretty similar to what we saw in FFXI for good ammo.

People still gets scarred about prices, but forgetting they have an extra "0" from what they were in FFXI. People may saw "but here you do 333 arrows in 1 synth" but here you also use a decent amount of materials, including some infamous glues that ckick the price up. I might be wrong since there's some time since i last bought them, but wing glue is supposed to be 5~10k a pop, which already put 15~30k at stack price since you need 3 per stack. Cockatice, swan and eagle fletchings are also kinda expensive (not as expensive as glue tho).

Anyway...IMO 90k a stack, depending of the arrow, is fair enough....and no, i'm not a carpenter that sells arrow =P
