USPS does that sometimes! They will occasionally take longer than 1-5 business days to ship, or will lose letters entirely. Please reach out as soon as you can if you're in need of your order urgently. I recommend triple checking the address before reaching out, ofte a missing apartment # can be the culprit.If you have time to spare before your trip, some orders have either bounced back to my PO box (which I immediately re-package and ship) or arrived at the customers mailbox up to 2 weeks after shipping, so it can be worth waiting and see.
