*Undercuts by 1gil 2 minutes later*

Looks at recipe realizes it takes 4 of something, lists 3 HQ 10 higher than your last list, then lists 1 single HQ 300 lower than the highest HQ listing, forcing you to buy all my stuff, or have an odd number of mats. No one likes having odd numbers of mats *now do we?*
