Decrease in supply doesnt mean that there will be a increase in demand.
it depends.
In santa's case, the price is over-estimated.
it is hard to say the price will remain or even boost again,
but what we know is that, the quantity of santa is only a little.
it deserved to be a high price but not the price now.
Wizard G can be found in clues so the price will not be boost as much as santa.
but it seems that it is being merched?
