We cover shipping (first-class USPS), as well as state and local taxes :)
Delays sometimes happen, as the mail system has drastically changed since Covid. We appreciate your patience- as well as your kindness should an issue arise.
All orders still go out same day on our end if ordered before 2:30pm EST- we know how important this is, and do our absolute best! Thank you!
