Exam Voucher ... Discounted?

Hey guys,

I'm looking to take the 220-801 this week or next week the latest so I need to get a voucher. I'm wondering if anybody knows where I can get the most discounted price since I really do not need a voucher that expires a year from now. I also noticed a couple of threads of individuals selling their spare vouchers so if anybody else has a spare to sell, I'll take it.

Thanks
