I paid $200 for this voucher, but no longer will be able to use it. I bought it during a promotion that allows a second free retake if you fail the exam. I talked with Sun and they assured me that I could sell the voucher to another person, but she wasn't certain how the retake would work. It's good until August 31st, 2007 and is for the full java programmer cert for 1.5--not an upgrade exame.
I'll sell it to the best reasonable offer that comes along. Please contact me at dean.harrington@comcast if you are interested. I'm in Minnesota, USA
