I send/receive First Class mail and small packages fairly often and itu2019s rarely longer than three business days if itu2019s to or from a city in California, meaning they can send on Monday and am confident Iu2019ll receive it in Thursdayu2019s mail, we donu2019t count the ship day. More rural and northern California locations may take an extra day or two, both ways. More than once Iu2019ve seen something ship on a Friday before cut-off time and arrive in Mondayu2019s mail. Itu2019s so fast that I wonu2019t pay for Priority Mail unless itu2019s over 13 ounces, the maximum weight for First Class mail and packages.
