Not worth the effort
I bought these to help pay for my cruise. The thought is that if I use my amazon credit card for these, getting my 5% cash back, then I’d save some money on my cruise that costs many thousands. Well, beware, folks. Gift card redemptions are handled by a 3rd party and Carnival Can’t see the card activity, balances, etc. when I tried to apply the gift card to the balance owed for my cruise booking, it got all jacked up and I had to have the 3rd party unwind it all and the they mailed me a replacement gift card 3 weeks later for the correction. What a mess. It wasn’t worth the 5% I saved going this route.
