Get a legit wine bottle mailing box from your local wine shop. This should be sturdy styrofoam in a cardboard box fit to the styrofoam forms. They come in 2-12 bottle sizes. Don't tell them it's wine, and if UPS or FedEx asks, it's "juice" which is not lying. Also, wrap the bottles in newspaper to keep them from shifting in the forms. FYI shipping booze across state borders or within certain states is illegal and they will most likely NEVER call you or care. Cheers!
