I got sent a book from the US through USPS - it was delivered at my home by MercadoLibre. No paperwork, nothing. Best of luck....!I’d like to send 2 small size lightweight books from the US to BA, max total value is $20, and plan to send it via USPS hoping to be delivered to door.. This would be a gift, and a surprise for my friend. Anyone who got books, did you need to file any paperwork, go and collect it, pay any duties ? Any experiences shared is appreciated.
