Help With Showing Random Number

Hi
I have a list of 100 coupon codes (e.g. abcd-1234) that I would like to randomly show to my users but as a hyperlink. So on page load it shows abcd-1234 or bcde-2345 or bcde-3456 but that code is clickable, when clicked goes to another page.
How do I do this? Thanks everyone.
