We've run into this same problem with some of our taller bottles or wider bottles. We've had custom made packaging - without styrofoam. The inserts are rolled up corrugated. We have boxes that fit one or two bottles, and boxes that fit up to six bottles - with separators for empty spaces, and three bottle carriers that convert to shippers. On the West Coast we used Box USA/International Paper which had some creative solutions. I'm sure there are similar box companies all around the country. If you have custom made boxes, you'll need to order enough to bring down the unit cost. We also bought pre-made packaging (with styrofoam inserts) from Coastal Products in Sonoma, CA when we suddenly had a bottle that didn't fit our other boxes.
