How does anyone ship brownies or cookies? FedEx or UPS of course.
I'm not asking you to send me a dime bag, that would be highly illegal, and break so many federal laws and get you and me in trouble if we're caught.
Now if you were to bake 'em . . . I don't know how anyone could tell when shipped.
j/k mang, don't risk this. I'll smoke you out if you're ever in L.A. or San Diego though.
