If your package is returned to our warehouse, grab a towel and don’t panic. We will send you an email asking for a new address to resend the package to. The reason we request a new address is to ensure that the package actually gets to you the second time around! If we had a dollar for every package lost by the USPS we would have enough money to start our own postal service (Not really, but you get the idea!) USPS is a mysterious creature, full of inconsistency and vague answers. What we can tell you is make sure to have your name and apartment/suite number clearly stated on your mailbox and your sidewalks are shoveled and clear of debris. Also confirm that your mailbox is able to fit a padded mailer inside, otherwise you may have to go pick it up at your local Post Office. Please send any other questions/comments to support@plugyourholes.com and we'll be happy to help!
