Thanks thats the one I was gonna buy until I found out you could only buy 1 voucher per ticket. I wanted to buy 2 vouchers. Driving up from Richmond to just meet 2 players wasn't really worth it to me.
save the $20 you would have spent on vouchers and get to a Sunday game instead, if you get there early enough you'll have time for 4 autographs (and a minimum of two).
