Will my FedEx package come today if it says on 'Fedex vehicle for delivery'?

Absolutely. FedEx Home Delivery, a division of FedEx Ground, runs Tuesday-Saturday. Since your order is going to a residential home and scanned on the truck, I guarantee you it is on a HD truck and headed to your house. Just remember, most drivers have to deliver 150-200 packages every day. So be patient with them! =)
