Don't worry! You can return all of your empty CO2 cylinders with the same shipping label. Once you submit your order online, we'll send you full gas cylinders along with instructions to print your DPD label for your empties.
Sparkle Note: In order to properly refund your deposit, please be sure to write your customer number on the DPD label in "Ref Box". Your customer number can be found in your account under "Order History".
