If you end a phrase with good luck do you use a exclamation mark?

Ending a phrase with the term 'good luck' does not require the use of an exclamation mark. The use of an exclamation mark is dependent on the meaning or tone of the sentence, not the use of any particular Word or phrase. There are instances in which the use of an exclamation mark after the phrase 'good luck' may distort the intended meaning, such as, 'I have not had good luck'.
