Don't do it. I ordered a basket of cookies for Valentine's Day that wasn't delivered until well after business hours, so the recipient didn't receive it until the next day. It took me six tries to reach someone on the phone, who was rude and offered nothing to make up for the failure. Her retort was that the cookies were delivered and that it was their busiest day of the year.
A delivery company that can't fulfill its orders within business hours and has incredibly rude customer support isn't deserving of your money. Go elsewhere.
