- JJJMay 18, 20262.0Workers are nice, but screw USPS. I mailed my mom a mother's day card (yes, only a standard hallmark card, nothing else) Only to have it sent back days later with the writing "owe $8.78" on it ??? I literally put the card in a new envelope (same size as before) & mailed it again, without issue, a 2nd time. So..that's cool. Sorry for the late card Mom.

- SHSarah HinsonAug 9, 20205.0The woman who helped me send my package was so very kind and helpful. Made sure everything was well packaged so it wouldn’t get damaged while shipping.
