Keep checking the internet Night. Do a google search, check amazon and ebay. If you can't ship it to your friend, can they ship it to you or another friend that can maybe deliver it? The packaging from Spectrum is very discreet, not sure about other suppliers.
Continue checking out headshops as well. Try a search for them online (not necessary those near you), where they could ship to you as well.
I wish you and your friend all the best.
