Okay so I have a toddler so we go thru alot of juice and milk in this house. I'm going to be giving her more juice than milk while we're there just out of convenience. I want to ship ahead about 30 juice boxes. Can I ship liquid? Have you done this? Did it leak? We won't have a car there for a grocery run and I'm not paying garden grocer's prices although I love their service. Any guidance will be appreciated! Thanks!
