Sometimes your tracking number says the package is delivered but you don't have the package. There are several explanations for this. Often the tracking isn't in real time and packages that say they are delivered but will reach you in the next few days. Sometimes the package is delivered to a neighbor and it's best to ask any neighbors if the package was delivered to them. Sometimes this means that the address given at checkout was incorrect or outdated. Our shipping system usually flags if there is an issue with an address but not if the address put in the system is a valid address that is just incorrect for you. In this case if you call your local post office they can sort this out for you. Depending on when you find this out the package may already be on it's way back to me. In this case I would be happy to resend but for incorrect addresses on packages I would require you to pay the additional postage fee. The carrier tried to deliver the package and was unable to for any number of reasons. Usually they leave a note but often times not. The carrier will attempt to redeliver so it is best to wait a few business days. Your package may be lost or stolen. If this is the case, you can open a mail theft case with USPS and let me know.
