I bought a few juices from TV and noticed that the Doublers don't have the same flavor as the ones containing nic. Is this "normal" for the doublers? I would assume TV mixes everything at once when they fill the order, and then adds nic to the bottle that requires it. Is this how it's done? I guess I just don't understand why the taste difference. By the way, even the samplers are more intense flavor-wise than what I received through a normal order.
