It depends when you ordered it. We use registered mail by regular postal services ...so it usually takes between 7 and 10 business days, depending on where you live in the US (obviously longer for California, don't know why, but that's fact).
I never received it. Never even a notice. The mail here in Brooklyn is inept at best. I have had a problem with books being sent to my address from time to time. Standard mail is best, I suppose-if you can do that. If not let me know.
