Less than one if possible. I bought a voucher for Rixos Limo for a Napa adventure for my daughter's 21st B-day. When the day finally came, I couldn't remember which site I had purchased from and consequently, the voucher expired. I came across it when I was cleaning out my desk and found that they do not follow the California law that says paid vouchers NEVER expire. Would love to start a class action law suit against them for the value of my voucher. Rixos Limosine wouldn't honor it either. I just wanted the value not the whole adventure.
