I’ve had nothing but great experiences with the post office. Everyone is so friendly and make sending packages easy and less stressful. I also love our mail lady Charity, she’s very friendly and handles our packages with care. I appreciate her company! Also love Allison too! We appreciate that they deliver them all the way to our door when they are too big for the mailbox. Appreciate all their hard work!

I’ve lost count of how many times I check my mailbox to see an “attempted delivery” letter for a package with zero effort to make a delivery. I have cameras to show no delivery attempts so my packages that I paid to be delivered gets held hostage until I can find the time to go stand in line for an hour to get it. I’ve had this issue for years now and it’s infuriating. Do better!
