This is certainly of limited interest, but if you bet the ponies at Hawthorne Race Course near Chicago here's a deal for a $50 voucher for $25. The key is that it is valid for betting, so it can take you twice as long to tap out (or the same amount of time, just at double your normal wager amount.)

# Redeem at Guest Services on the first floor grand stand.
# Valid for betting or transferable for dining certificates.
# Valid during LIVE racing only.

Good luck!

Edit- Looks like limit is 2, and $3.75 for shipping.

Thanks OP. I usually feel like I've lost half my worth whenever I'm in Cicero!
