Beware of buying deal-a-day vouchers for Seamless - make sure they actually have restaurants in your area. They indicated they had a lot of restaurants for delivery near me. I thought it is a great concept and bought the voucher. I live a stone's throw from the largest airport in the country and there are literally hundreds of restaurants within a mile of me. Yet every time I tried to use the voucher, there were either none available or one that I didn't want to use.
They kept promising more restaurants but the voucher expired. I contacted them and they said I have to order something and then they will credit back the cost of my voucher (not the promotional value). I spent a better part of an hour driving to one (none would deliver), submitted my receipt as requested and they reimbursed me for 20% less than I paid.
I tried contacting them but have tired of trying to explain the situation over and over. They can keep the money; I won't use them again.
