How can I pay less for shipping on a cylinder exchange?

When ordering a CO2 refill at SodaStream.co.uk, you just pay the price of the CO2 and are then sent a pre-paid shipping label to return your empties.

We recommend exchanging 2 or more cylinders, so you can save in shipping fees. If you only have one cylinder to exchange, we suggest checking our store locator so you can easily exchange your CO2 cylinders at the nearest retail location.

Pro-tip: SodaStream recommends keeping a back up carbonating cylinder handy so that when one cylinder runs out, you simply swap the empty cylinder for a full one.
