Business days are Monday through Friday, excluding federal holidays within
the United States. Orders are processed by the following business day, and shipped from either our fulfillment center in Allentown, PA, or our office in San Francisco. We regret that we are currently unable to ship packages to P.O. boxes. Typically shipments in the US will arrive in 2-6 days, while those for Canada will arrive in 7-11 days for UPS Ground and 4 to 6 weeks for Parcel Post.
