Explanation= Yoshida was probably as annoyed by 1 gil per normal arrow price just like us 1.0 players were.

Any real reasoning can be stated to one of two things, we're the WoL and people just give us arrows because "Hey the WoL has a bow, I bet he could use some arrows for that, here no charge" or The GCs provide us our supply and we just kinda get them delivered by our glorious mail moogles ala Moogle PS.

Then there's the old cop out answer, "Itz magics bro, don't questionz da magics"
