I'm not sure who is managing this promotion for them but, if they are located in Delray Beach, Florida they are legit and I believe they were bought out by a British tour company last year.

They do this type of promition for a lot of major companies.

You will get a cert where the discount increases as the fare does. When I called to use mine last fall I was able to use one certificate and book two tickets for the same itin and got the discount for both tickets.

If you can provide the name I might be able to confirm that it is the same outfit.
