So, the real question is still 'Can bud be shipped, and if so...which service?'. I often think about live plant companies, who ship grandma her 'annuals' or my fiance's cut roses. Slip a z in that package and who would know the difference?
Not sure how much of this thread you've read - but if you're going to ship it use ONLY USPS!!!!!!!
And yes, it can be shipped - hell tons of it are likely in transit around the globe at this very moment. TONS!!!
Heh. Seriously though pack it well, be creative, and fudge the return addy
