Speak your mind while being polite!

Original sentence: “Nothing under $5.00 If you don’t like the price, to bad.”

Corrected sentence: “Nothing is under $5.00. Price is non-negotiable.”

The original sentence is rather uncouth. It would be more appropriate to phrase it in a more formal manner as in the 2nd sentence.
