I never got the Tranex,(only Alprax), but Raj just e-mailed me today .....

Friend I am sorry to say that I dont have stock of alprax with me. I have tranax and in both the salt is the same only company and brand name is different so I dont think it matters which one you get. But if you want you can change your order now. Regards ....

So I guess it's not an option to cash in the offer for now
