It is still too expensive

There was an old woman, who who was very deaf and who thought everything
too dear.

One day, she went into a shop and asked the salesclerk, " How much this stuff?"

"Seven dollars, Madam, it is very cheap." The lady said.
"It is too much, give it to me for fourteen."

"I did not say seventeen dollars, it is only seven."

"It is still too much," replied the old lady, "give it to me for five."
