Use UPS or FedEx. Pack it really well. A thick layer of crumbled up newspaper and individual bottles wrapped in a payer or two of bubble wrap and sealed in a ziplock (in case a bottle breaks). I actually use two ziplocks per bottle. Make sure the box is sealed up BEFORE you drop the package off and if they ask what is in the package, just tell them home made BBQ sauce, or jelly, something like that which would be in bottles.
