Computer systems for facilitating the sale and distribution of vouchers (e.g., restaurant vouchers) that may, for example, only be redeemable during a particular time window on a particular day. The system may display fixed prices for vouchers or allow consumers to bid on day and/or time-specific vouchers having a particular value. The system may sell the same day and/or time-specific voucher at different prices and set the price of the voucher based on, for example: (1) purchaser/bidder status; (2) the number of the vouchers that have already been sold; or (3) a substantially random methodology. The restaurant may set fixed criteria that must be satisfied before the system will award a bidding consumer a particular voucher. In other embodiments, in cases where a particular bid does not satisfy a pre-determined set of minimum bid criteria, the system may facilitate direct negotiations between the bidding consumer and the restaurant.
