UPS has as its policy (or so I am told) that they will not ship any alcoholic beverage from an individual. Thus, there is no way to do it with the knowledge of UPS, leading you subterfuge if you want to ship via them. I have heard numerous stories about wine shipments being seized and emptied, so there is no question what will happen if they discover it in a shipment. That being said, I have heard *cough* that double boxing it in a shipper within a larger box does improve one's odds of evading discovery. You're still running the risk of being found out, of course. And, yes, Fed Ex, does seem much safer for these purposes. What I have done in the past is to use a cooperative retailer to ship, but that relies on having one handy.
