I'm not seeing that. My seat is still the same price. Unless, as is quite likely, I'm missing something.
Oh, that's interesting. You have to enter it directly from the link in the email I've got...it doesn't work otherwise. If anyone does want a 50% discount then drop me a line and I'll forward you the email I've got which does include the 50% discount. (Or one could just make an even more ridiculous offer for my ticket, of course)....
