Why are divorces so expensive? Because they are worth it.
Supply and demand. If people want it, you can charge more. If people don't want it, you can't give it away.
(kinda like Justin Bieber or Miley Cyrus concert tickets)
Buy it at a dollar store. It is ,you guessed it, a dollar there. It works fine.
Not sure about the price in U.S.A
but In my place (250ml, 8.5ml oz) wish is the cheapest of all costs around $16 U.S,
the others can go about 6 or 10 dollars more.
I might as well die of cancer.
But seriously why is it so expensive, I don't understand.
