If you don't mind a slightly thicker tubing, you can go to a hardware store or homedepot and get a coil of 1/4 OD 1/8 ID clear vinyl tubing. It's much cheaper and the thick wall means it will be much more co2 impermeable. It's stiffer than aquarium vinyl so sometimes it helps to warm it up with hot water to slip it on to a hose barb.
