I haven't been through a summer vaping yet but I hadn't considered the summer shipping problem. Does it really mess things up. I guess the juice could expand and cause leaks. Is that what you are talking about. I'm not in Texas but Oklahoma gets pretty warm, especially last summer, so I can see how it might be a problem. I have a local store but I like my juices from several different vendors across the country. I will have to think about this! I am not sure my postman would make the trip from his truck to my porch for the cooler but I might have to ask.
