It didn't seem scientific or according to pure economic theory of supply & demand
It appeared like buyers just fixed prices arbitrarily
Now I know better
Here's what happens
Sellers individual offer high prices of their goods
If they notice its being bought at that price, the next person raises their own price, and so on
But if no one buys at the high price, they go lower bit by bit
Until they refuse to go any lower
And they become coy when they notice it is abundant
In the same way, sellers are eager to drop prices when they notice buyers are few, and also do "shakara" when they are many
Hop you've been enlightened!
