I have some flavor concentrates that I personally don't like. I am willing to trade for just about any flavor concentrate on the market. I have almost a full 30ml bottle of flavor west's watermelon and another 30ml bottle almost full of flavor west raspberry. I also have a opened but not used 15 ml bottle of capella's Boston cream pie I also have half of a 15ml bottle of capella's Boston cream pie. I don't enjoy these flavors but maybe someone has a use for them. Feel free to trade flavors you don't like as well I just figure that at the very liest I can try some new flavors good or bad that way no will no if they are good or not. Again I will trade for any of your unused flavor comncentrat!.
