Three Answers:
1) The Shop is closed for 5 more days, so you'll have to wait.
2) Toribashem's head texture shop IS NOT A CHARITY! You pay for a head or you don't get it, SIMPLE.
3) If you are poor then you'll have to barter with Toribashem for a price, but the lower the price I'm sure it means the lower the quality.
Good Day.
