You can have up to $2,000 worth of City Bites in your account, on any given day.  This means that the value that remains in and has been redeemed from your account at the end of one day, combined, may not exceed $2,000.  Therefore, for example, if there are 1,500 City Bites in your account and you have redeemed 500 City Bites that day, you cannot receive more than 500 City Bites into your account that day.
