When I track the status of my order, it says it was delivered but I can't find it. Where is it and what should I do?

“Please check the following: Verify the shipping addressLook for a notice of attempted deliveryLook around the delivery location for your packageSee if someone else accepted the deliverySome packages travel through multiple carriers; check your mailbox or wherever else you receive mail.Wait 24 hours - in rare cases packages may say delivered up to 24 hours prior to arrival”
