Now, seriously, something for free has not a price = 0, it has
NO price, that's what null is for; we use zero for the lack of
null.
Actually a price can be 0, say if you have a sale that gives 100
% off then the price doesn’t magically disappear. It could be
that the 100 % off is only for specific people or businesses. Or
that they pay fees instead of the price of a product, in which
case there’s a fee price but a product with the price of 0
because otherwise you’ll have accounting problems since you can’t
make accounting on records without prices, because mathematically
that makes no sense.
