Price drops?

[cruiser4630]

From time to time I see a post here about people taking advantage of price drops. How does this work? Are these new deals via email, VIFP special offers found on carnival's site after logging in, and/or do you just check prices on carnival's public website? Specifically: I booked a cruise yesterday and today I got an email containing an offer for the same cruise for the same price but with $100 on-board credit. Can I call Carnival and take advatage of this? Possibly pertinent info: I booked a balcony where Carnival will select my stateroom prior to boarding. I also booked it through Delta's website to take advatage of 3x skymiles. Thanks in advance to everyone willing to explain the ins and outs of price drops!

You will need to call and talk to the delta people.

Yup, carnival won't talk to you directly since you booked thru a 3rd party.
