Kujacker, for sure try to file a claim with USPS. Its very possible they delivered it to the wrong address. I had that happen a few years ago. Package showed delivered, but not to me. About a week and a half later I got a phone from some random guy in the next town over. My package was delivered to his address (address and name not even kind of similar to mine) He was unable to bring the package to me, and USPS refused to pick it up and deliver it to me, so he tried to google for a phone number for me. I was able to get my package back that same day. (there is a whole long, funny story about picking it up. The guy legit had a zoo with all kinds of fancy birds and a Capybara that lived in the house).
I live just north of Seattle. a lot of the neighborhoods have their own little Facebook groups and Nextdoor groups, try posting in those for your area. Maybe someone accidentally got it and has not been able to deliver it to you yet!
