$10 for $25 Restaurant Gift Certificates. Will you find these vouchers cheaper later in the month? Absolutely! Will there be a greatly reduced inventory by then? Absolutely! They usually restock inventory at the beginning of the month, but this month they added a group mid-month, so there’s a good chance the restaurant you’re looking for will be available. By the 30th? not so good a chance… Remember, Restaurant.com vouchers never expire and if a restaurant closes or leaves the program, your voucher is automatically placed in your account as a blank certificate.
