We'll wrap up the old year with a "chestnut" teaser for today's Friday Free-for-all challenge at the mentalfloss.com Brain Game. Good luck:

A lady goes to a hardware store to make a purchase.
"They're only 40 cents each," the salesman tells her,
so the woman replies, "Great, I'll need 250."

The clerk fills her order and informs the customer
"That'll be $1.20, plus tax" before ringing her up.

How is this possible?

Here is the SOLUTION.
