En menos de una semana he tenido una pésima experiencia con la entrega de mis paquetes , no sé si será un nuevo repartidor o lo que esté pasando pero ya van dos ocaciones donde me entregan el paquete roto o sin ningún artículo , hace unos días lo dejaron a mitad del patio porque no cabía en el buzón en lugar de dejarlo en la puerta , estaba totalmente destruido y se perdió una de las 2 sandalias que venían dentro y el otro paquete lo dejaron abierto y sin nada dentro del buzón . Quien responde por eso ? Porque vas a la oficina y no están los artículos

We have lived in Key Largo for six month and already 4 of our packages have been delivered to different houses. Fortunately, I have neighbors that are kind enough to bring them to me. (one woman told me she tried to give it back to the mail carrier and he claimed his truck was "too full"). They don't take photos either so you have no idea where the problem arose. In addition, the amount of mail we get for other houses is quite alarming. While living in our last home, we never had a package shipped USPS not make it to us in over ten years. I know that going to the office, or complaining in any way, will do no good so this is my next best option. I see my mail carrier on her phone almost every day, barely glancing at her deliveries. If you live in the area and need something to get to you, go with UPS or FedEx or there will be a good chance it doesn't make it.

This location has so very nice and helpful workers. I was able to track my package back here and they held them for a day so it would not get sent back. They have mailboxes for a good price for seasonal visitors.
It is hidden and my gps told me where to turn at the last minute. So be ready when it shows you are close to the destination.
