Yes, because you only wanted to buy one cruise next which would have cost you $150…. But by saying you didn’t want the OBC, they talked you into spending another $100 that you didn’t want to spend in the first place.
They call it OBC but it’s not really, it just offsets the price of the CN.
1 CN for total of $150 (value of $250)
2 CN for total of $250 (value of $500)
3 CN for total of $375 (value of $750)
4 CN for total of $500 (value of $1000)
