It seems that they are generating more than just a healthy chunk of the revenue portion with low overhead costs and heavy trends circulating the net. Do you have any experience dropshipping these products? Can you speak on the viral aspect of their marketing? I don't believe they require any licensing to sell but I could be mistaken. At any rate, they are booming, and I've seen drums of herbal powder from wholesale hookups at a price that could have over a 500% margin at least... I plan to see what the buzz is all about for myself.
