What day should you get a package delivered from San Fransico CA to Houston TX if it was brought to the post office Friday afternoon?

What shipping service was used? If it was mailed via USPS Express Mail, it will be there the next business day. If it was mailed via USPS Priority Mail, then it will be there in about 2 or 3 business days (though this is NOT guaranteed). Items mailed via USPS First Class typically arrive in 2-5 business days (again, not guaranteed). Parcel Post (and similar services like Media Mail or Library Mail) typically arrive in 5-7 business days.
