And then....there are people like me who vape the same juice all month, as I make it myself. I can't have smelly juice on the boat I work on, it annoys the Captain. So, we agreed, to this one slightly caramel flavor, as that did not annoy him. Other flavors seem too strong now. I make about 240ml of it at a time, lasts for a few months. (I freeze what I am not using. And it stays fresh) And it costs me about $2.40 for 30 ml! I make up for the low cost by buying good gear and rebuildable tanks atomizers. For me the flavor changes when I eat or drink or after brushing my teeth. Vape On!
