I had a (rather valuable) package that was supposed to be delivered to me via UPS. However, USPS accidentally picked up the package. I have no idea if it actually made it close to me and is now being held by USPS as dead mail, but how can I get them to check? When I went to my local branch, they said they cannot check without a tracking number. I told then that number doesn’t exist because it USPS picked it up by accident. They don’t want to help past that.

I was wondering if there are any quality youtube videos - either a set or a single video - that have improved your dentistry, or taught you a deliverable skill? Would love to build a compendium of knowledge, thank you!
