Saturday is not considered a next or 2nd business day. If you need delivery on Saturday, please be sure that someone will be at the destination. If no one is there, you will pay the additional Saturday delivery cost but delivery will not be made until Monday. Holiday's are generally observed and services are not available.
Many companies observe two day holidays at the end of the week.
In this case, delivery may not be made until Monday and some other delivery method might give you the same results but be less expensive. Post Office box addresses are good only for US Express deliveries. All others need a street address. ALSO, the telephone number of the recipient is very important and can speed up some deliveries. Please complete the card in its entirety.
