Jynxy, not sure where you learned matth but 12x30mins is 6 hours. So you would need 2 red curries to equal 1 stack of buns. Therefore the price is about equal unless you die alot.
These really should be selling around the 85-100k range. Making curry is expensive then turning that curry into buns can sometimes case a loss of gil. I hope the price on the buns continues to rise.
