I think there would be takers even for $800 if it was cash but other commenters have pointed out that united never offered money but rather travel vouchers in small denominations that you cannot use more that one of in a single transaction.

I can offer $100k in thanksgiving fun bucks as well every time I screw up majorly. It will be in denominations of $50 and you can use them towards future consulting with me. My consulting starts at $100 per hour with minimum of one hour. You cannot use more that one voucher per transaction.
