Do you have or know where to find disconts on Carnival Cruiseline?

I’m booking a last-minute Carnival cruise and would like to get my hands on discount voucher on online discount code. Please let me know if you know where I can find one. Thanks!

I just received an email from Travelocity today for Carnival cruises, last minute, for as low as $179. You may want to sign up for their email deals.
