The mail service is horrible. They always come up with an excuse for why they weren't able to deliver my packages when some things can go inside mailbox. I usually don't have a problem but lately it has been an issue and it is really getting annoying

Usually I have a great experience with USPS but today not so much. Came home to find a package stuffed inside my mailbox to the point that it took 10 minutes to get it out. Luckily nothing was broken.

I shipped a package on May 4th and intercepted it on May 5th and it STILL has NOT delivered. I paid $19.95 to do this - NOT HAPPY!
