I need to change my address how can I do this plz

I only knew of address change at post office

I missed understood your question, yes you will have to change your address with the Post Office

If you shipped this package through our store we can make the changes, I would need to the following the phone number that was given when filling out our paperwork and your name that was given. What is the correct address, if you happen to have the tracking number that would be great.
