Be aware that when a child has requested an item and it is available for pickup, the Material Pickup Notification will show the SPONSOR as the customer but will have the child's CARD NUMBER listed. Don't let this confuse you - The SPONSOR is the person financially responsible for the CARD NUMBER listed on the notice. So when you're looking for an item on the reserve shelf, you should look according to the SPONSOR's name and check it out on the CHILD's number. This process becomes interesting when the child's last name is different from the sponsor's last name.
