I used traveller's cheques all the time. They actually saved me when I had my hotel room broken iinto once and they were all stolen (this did not happen in Jamaica btw). Anyway, I had all my money rturned to me that same day.

However, as much as a big fan I was of traveller's cheques, I can see how the debit card has made them somewhat redundant.

I would suspect as well that because they are unpopular these days it is probably just not worth while for the cambios to continue to support them.
