Vouchers are in increments of $5 usually, at least for me they are though I have seen $10. And you don't get change. So no sense using a voucher on a $3 purchase. If a beer is normally 10 bucks, SSH day it's $7.50, you'd pay $2.50 cash plus a $5 SSH voucher. Also you can't use them at Fridays and I don't think the walking vendors will take them. I think you have to actually go to a stand. That's all accurate. They're good at the stands or in the team stores. There's also no change, so as pointed out, if your purchase is $6, you'd only want to use one voucher and pay the difference in cash. You can the most bang for your buck on the SSH days obviously, as you can combine the two. That's what I was getting at. So if I ring up a $40 face value bill on an SSH night, I only have to use $30 in vouchers on it?
