Best Things to Buy Before Cruise in Carnival Cruise Lines Posted June 20, 2016 Bring a can of Pringles and some candy if you like. I've seen Pringles priced at $10 before and I'm sure people pay it because they just want some damn chips. That made me LOL!! BECAUSE....I have gotten off the ship and went directly to a gas station and picked up chips!! haha Weird how I missed them of all things!! And I don't even eat chips on a daily basis on land!!
