Please follow this link and apply for a free $200 voucher! It appears that the trips themselves are still quite expensive - quick look and they start at $7500 or something - hope it may help someone though!

Couldn't find it in me to post it as a deal on those prices. I do not condone the reselling of these vouchers but that is at your own discretion!
Enjoy! :)
